Question

Find the volume of the specified cone. Use 3.14 for Pi, and round your answer to the nearest whole number.

Radius = 4 in., Height = 9 in.
a.
301 cu. in.
b.
226 cu. in.
c.
75 cu. in.
d.
151 cu. in.

Answer 1

D. 151 cu. in.

Explanation:

Given: Cone; Radius = 4 in, Height = 9 in.

To find: The volume of the specified cone

Formula:
`V=(1)/(3) h\pi r^2`

Solution: A cone is a solid that has a circular base and a single vertex. To calculate its volume multiply the base area (area of a circle: π × r²) by height and by
`(1)/(3)` : volume = (
`(1)/(3)` ) × π × r² × h.
