Question

A cone has a height of 2.5 in. and a radius of 5 in. What is the volume of the cone? (Use 3.14 for . Round the answer to two decimal places

Answer 1

V=(hπr^2)/3, we are given that h=2.5in, r=5, and π≈3.14 so:

V=(2.5*25*3.14)/3

V≈196.25/3 in^3

V≈65.42 in^3 (to nearest hundredth of a cubic inch)

Answer 2

Volume of cone is 65.42 in²

Explanation:

Height of the cone, h= 2.5 in

Radius of the cone, r = 5 in

Volume of Cone =
`(1)/(3)\pi r^2h`

=
`(1)/(3)*3.14*5^2*2.5`

=
`65.42\:in^2`

Therefore, Volume of cone is 65.42 in²
