What is the surface area of this rectangular pyramid? 5 cm 5 cm 5 cm square centimeters​

A tree struck by lighting broke at a point 13 ft above the ground as shown. What was the height of the tree to the nearest tenth of a foot?

13² + 38² = c², so 169 + 1444 = c², 1613 = c², and 40.2 ≈ c.

Add this length to the height of the bottom tree: 40.2 + 13 = 53.2 ft.

The height of the tree was about 53.2 ft.

Answer:

its either 2 or 4 because a triangle can't change its shape it need to be the same shape

Answer:

2, 3, and 4.

Step-by-step explanation:

  The only answer that would result in a non-congruent triangle would be Option 1. It is asking you to dilate by a scale factor of 2 which would make the triangle 2 times bigger. In that case, the triangle to not be congruent.

  Reflections, Rotations, and Translations do not change the size of the triangle which means it remains congruent.

Step-by-step explanation:

The approximate difference in their volumes is 17.2 cubic inches

A sphere is a round solid figure, with every point on its surface equidistant from its centre.

The formula for calculating the volume of a sphere is;

V = 4/3πr³

where:

r is the radius of the sphere

Given the following

diameter of youth ball =2.8in

radius of youth ball r = 1.4in

diameter of adult ball =3.8in

radius of adult ball R = 1.9in

Determine the difference in volume

D = 4/3π(R³ - r³)

Substitute

D = 4/3π(1.9³ - 1.4³)

D = 4/3π(4.115)

D =17.2 cubic inches

Hence the approximate difference in their volumes is 17.2 cubic inches

Step-by-step explanation:

Answer:

Below!

Step-by-step explanation:

Since there is a variable (x) on the L.H.S and a constant (-7) on the R.H.S, the line will be a vertical line intersecting the x-coordinate (-7).

~Graph attached

Determining the y-intercept of the line:

Since the line is a vertical line, it's y-intersept is undefined as it will never intersect the y-axis.

Determining the slope of the line:

To determine the slope of the line, pick any two points that is on the line.

Using the slope formula (y₂ - y₁/x₂ - x₁):

∴ Any number divided by 0 is undefined

Thus, the slope and the y-intercept are undefined.

So

line will be parallel to y axis

no y intercept as parallel to y axis means it will never intercept y axis

Asuming this is a triangle: C = 32.5

Step-by-step explanation:

Asuming this is a triangle:

Use the pythagorean Therom:

[tex]A^2 + B^2 = C^2[/tex]

[tex]26^2 + 19.5^2 = C^2[/tex]

[tex]676+380.25=1056.25[/tex]

[tex]C= \sqrt{1056.25}[/tex]

[tex]C= 32.5[/tex]

Answer:

C

Step-by-step explanation:

Lets look at all the answer choices:

A and looks like a little number.

B said 7. 7 x 16 = 122 7 x 12 = 84.

122 + 56 = 178. 140 + 84 = 224.

B is incorrect

C said 21. 21 x 16 = 336 21 x 12 = 252

336 + 56 = 392 and 140 + 252 = 392

C is the correct answer.

Step-by-step explanation:

the area of a circle (all 360°) is

pi×r²

with r being the radius.

the area of a circle segment is just the corresponding fraction of the whole circle.

so the area of a segment of x degrees is

pi×r² × x/360

in our case we know

pi×42240² × x/360 = 180 mi²

we also know that there are 5280 ft in 1 mile.

so, the radius is actually

42240 / 5280 = 8 miles

and therefore our equation resulting in mi² has to use miles and not ft and has to look that way :

pi×8² × x/360 = 180 mi²

pi×64 × x/360 = 180

pi×64 × x = 180×360

pi×x = 180×360/64 = 1012.5

x = 1012.5/pi = 322.2887598...°

so, the angle of the segment of a circle with the area of 180 mi² and the radius of 8 mi is 322.2887598...°

Answer:

Exterior angle.

Step-by-step explanation:

by my analysis

if hey said triangle XYZ

it should mean each exterior angle is named either X, Y, or Z.

so angle Y should be an exterior angle (outside angle).

but the angle formed by X and Z will be an interior angle (inside angle).

Answer:

247.42 m^2 to the nearest hundredth

Step-by-step explanation:

The surfaces area of the side of the cylinder = 2πrh

= 2π(1)(6)

= 12π m^2.

Now we need the surface area of the cube minus the 2 circles at each end of the  cylinder

= 6^3 - 2πr^2

= 216 - 2π

So the required surface area

=  12π + 216 - 2π

= 217 + 10π

= 247.4159 m^2

Answer:

77.5 square units

Step-by-step explanation:

set up a proportion first.

then, cross multiply

2x = 155

divide by 2

x = 77.5

The area of the base of the larger prism is approximately 193.75 square units.

If two prisms are similar, then their corresponding sides are proportional. Let the smaller prism have a base area of 31 square units, and let the corresponding side of the larger prism have length x.

Since the ratio of similarity is 2:5, we have:

x / s = 5/2

where s is the length of the corresponding side of the smaller prism. Solving for x, we get:

x = (5/2) x s

We know that the area of the base of a prism is given by the formula:

A = s²

Substituting the value of s in terms of x, we get:

A = ((5/2) x s)²

A = (25/4) x s²

Substituting the value of s² in terms of the area of the smaller prism, we get:

A = (25/4) x 31

A = 775/4

A = 193.75 square units

Therefore, the area of the base of the larger prism is approximately 193.75 square units.

Answer:

use area

Step-by-step explanation:

we can't use volume here since we are dealing with the outside part only

so area of a cylinder is =πr²h

our r represents the radius which is diameter/2

r=7.5/2

=3.75m

our h represents height which is 12.5m

so put in our formula

area = π×(3.75)²×(12.5)

=552.2330836m³
