Find The Circumference And The Area Of A Circle With Radius 3 MUse The Value 3.14 For , And Do Not Round

Answers

Answer 1

Answer:

The area: 28.26m^2, the circumference: 18.85m

Step-by-step explanation:

The area of a circle is 3.14(3)^2, which is 28.26, the circumference is 2(3.14)(3)=18.85m.

Answer 2

Answer:

Area of a circle= π[tex]r^{2}[/tex]

3.14 x [tex]3^{2}[/tex] = 18.84

The area of the circle is 18.84 [tex]m^{2}[/tex]

Circumference of a circle = 2πr

2 x 3.14 x 3 = 18.84

The circumference of the circle is 18.84 m

They are both the same number but the area is squared.

What is the volume of the following figure?
A. 40
B. 50
C. 30
D. 20

Answers

Answer:

C

Step-by-step explanation:

L x w x h

2 x 3 x 5 = 30

hoped this helped :)

First off, the formula for volume is :
length x width x height
Or
base x height

Assuming the each unit is 1, there is 2 rows of 3, or 6 units as the base.

There are 5 units up, representing height.

So, you multiply 6 x 5, and get 30.

Therefore, your answer should be C!

Answer: This is the best I could find for you

Step-by-step explanation:

"When the ratio of part to whole is equal to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion."

How do you find the probability of two events A and B when A and B are independent? dependent?

A.For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event, and then multiply.

B.For independent events, find the probability of the first event, find the probability of the second event, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply.

C.For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then add. For dependent events, find the probability of the first event, find the probability of the second event, and then add.

D.For independent events, find the probability of the first event, find the probability of the second event, and then add. For dependent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then add.

Answers

Answer:

I think it is A, but i am not sure, sorry

Step-by-step explanation:

Two events are independent if the result of the second event is not affected by the result of the first event. If A and B are independent events, the probability of both events occurring is the product of the probabilities of the individual events.

A. For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event, and then multiply.

Probably A

What is the maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm?

Answers

Answer: The volume of box is 6×8×10 cm^3

All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60

Step-by-step explanation:All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60

Answer:

50 cubes

Step-by-step explanation:

The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.

You can find this by dividing the total volume of the box (10 x 8 x 5 = 400 cm^3) by the volume of a single cube (2 x 2 x 2 = 8 cm^3). So 400cm^3 / 8cm^3 = 50 cubes.

Hence, The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.
