Question

@iGreen Same thing as before?

Answer 1

What is the approximate volume of a cylinder with a diameter of 14 meters and a height of 10 meters? Use 3.14 for pi.

A.
219.8 m^3

B.
439.6 m^3

C.
1538.6 m^3

D.
6154.4 m^3

Answer 2

Approximate, so you plug in 3.14 for pi.

\(V = \dfrac{1}{3} \pi r^2 h\)

Answer 3

Confused on this one, due to "diameter" and not Radius

Answer 4

Diameter is double the radius, so divide by 2 to find the radius.

Answer 5

Sorry, I just accidentally closed my window.

Answer 6

its fine lol. so divide diameter by 2?

Answer 7

14/2 = 7

Answer 8

Yep

Answer 9

10 times 3.14 times 7^2(Simplifying after that)
10 times 3.14 times 49

Answer 10

31.4 times 49

Answer 11

1538.6?

Answer 12

C?

Answer 13

Oh..this is a cylinder..not a cone.

Answer 14

So we take out the 1/3.

Answer 15

Yeah, C is correct.

Answer 16

Thanks.
