Question

Find the volume to the nearest hundredth using 3.14 instead of pi.

Answer 1

48π ≈ 150.72

Explanation:

The volume formula is V = 1/3Bh

The base area formula would be πr²

Since 8 is the diameter, 4 would be the radius

Now plug that in, π (4²) = 16π

Now multiply that by the height, 9, and get 144π

Multiply again by 1/3 and you'll get 48π

Answer 2

150.72 ft^3

Explanation:

The volume of a cone is

V = 1/3 pi r^2 h

We need to get the radius

r = d/2 = 8/2 =4

V = 1/3 (3.14) (4)^2 *9

V = 1/3 (3.14) 16 *9

V =150.72

Rounding to the nearest hundredth

V = 150.72
