Answer:
Step-by-step explanation:
Formula
V = (1/3) pi * r^2 * h Substitute the givens into the formula
Givens
V = ?
pi = 3.14
r = 3 in
h = 18 in
Solution
V = 1/3 * 3.14 * 3 * 3 * 18
V = 169.56
Answer
V = 169.56 in^2
A cone has a radius of 3 inches and a height of 18 inches what is the volume?
Explanation -:Given:
Radius of a cone = 3 inchesHeight of a cone = 18 inchesNeed to find :
Volume of a coneSolution :
We know,
[tex] \small\boxed{ \sf{ Volume_{(cone)} = \dfrac{1}{3} × π × {r}^{2} × h}}[/tex]
Where,
r stand for radiush stand for heightAssuming π as 3.14[tex] \small\rm Volume_{(cone)} = \dfrac{1}{\cancel{3}} × 3.14 × { \cancel3} × 3 × 18[/tex]
[tex] \small\rm Volume_{(cone)} = 3.14 × 3 × 18 = 169.56 \: inches[/tex]
Hence the volume of the cone is 169.56 inches.[tex] \rule{74mm}{8pt}[/tex]

15) A, B, C, D, E and F are towns situated as follows. * A is 30 km east of D * C is 20 km east of E * F is 10 km west of B * D is 10 km south of F * A is 10 km north of C How far would you need to travel to get from B to E?
Answer:
Option D: 20km South
Step-by-step explanation:
Lets say A = (0, 0)
Finding B:A is 30km East of D which makes D = (-30, 0)
D is 10km South of F which makes F = (-30, 10)
F is 10km West of B which makes B = (-20, 10)
Finding E:A is 10km North of C which makes C = (0, -10)
C is 20km East of E which makes E = (-20, -10)
Finding the answer:Find distance from B = (-20, 10) to E = (-20, -10)
1. Cancel equivalent values:
x of B = (-20) and x of E = (-20)
Remove x from equation.
2. Solve for answer:
B = 10 and E = (-10)
Find the difference: (-10) - 10 = (-20)
Conclusion:
South translates to negative on a graph making the answer 20km South

Optimize the equation P = 3x + y using the constraints
x ≥ 0, x ≤ 4, y ≥-1 and y ≤ 5.
What is the maximum?
Answer:
P = 17
Step-by-step explanation:
let's separate this into x and y components
x component: 3x
as x increases, so does the x component. e.g. 0 * 3 = 0, 4 * 3 = 12. therefore, we want x as high as possible
y component: y
as y increases, so does the y component. this is because the y component is literally just y.
therefore, given these two, to maximize P, we want x and y to be as high as possible
in 0 ≤ x ≤ 4, the maximum of x is 4
in -1 ≤ y ≤ 5, the maximum of y is 5
plug these in to get
3(4) + 5 = 17 as our answer

Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use the equation b=0.29h+1.35 where b is the size of the BMX bike frame in inches and h is the height of the rider in inches.
Answer:
(a) 1 inch of rider ⇒ 0.29 inches of frame
Step-by-step explanation:
The "slope" in the equation is the coefficient of the independent variable. Here, that variable is "h", and its coefficient is 0.29. That is, the height of the rider is multiplied by 0.29 (and a constant is added) in order to find the height of the frame.
__
The meaning of the value 0.29 is that a 1 inch increase in the rider's height should result in a 0.29 inch increase in the height of the frame of the bike.
The question asks for an explanation of the slope, not its function in the equation. That is why we have chosen the first answer.
Answer: inch of rider ⇒ 0.29 inches of frame

A restaurant bill is $25, and a 20 percent tip should be given to the waiter. Which expression can be used to find the total amount that will be paid?
25 dollars times 0.02
25 dollars times 0.20
25 dollars times 1.20
25 dollars times 2.00
Answer:
B. 25 dollars times 0.20
Step-by-step explanation:
When finding the percentage, you shift the percentage you want two places to the right. In our case we have 20.00, so shifting the 20 two places to the right would give us 0.20.

The diameter of a circle is 100 cm. What is the circumference of the circle? (Use 3. 14 for π. )
Explanation:
Use the formula C = pi*d
We're multiplying 3.14 by the diameter 100 to get 314, which is the approximate distance around the circle (aka perimeter). The value is approximate because pi = 3.14 is approximate.
