Question

Find the volume of a cone with the height of 9 m and a base diameter of 8 m use 3.14 for pie and do not round answer

Answer 1

Volume of a cone = 1/3 × pi × radius ( squared ) × height .

radius = diameter / 2
= 8 / 2
= 4 m

height = 9m
pi = 3.14

volume = 1/3 × 3.14 × 4^2 × 9
= 1 / 3 × 3.14 × 16 × 9
= 150.72 meters cubed

HOPE I HELPED !!

Answer 2

Alright, this is what you do: the volume of a cone is 1/3 pi r^2h
first step: V= 1/3 (3.14) (4)^2 (radius- twice as small as the diameter) (9)

2d v= 1/3 (3.14) (16) (9)

3d (multiply 3.14x16x19)

4th divide by 3
