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

Answer:

Volume of cone is 65.42 in²

Step-by-step explanation:

Height of the cone, h= 2.5 in

Radius of the cone, r = 5 in

Volume of Cone = $\frac{1}{3}\pi r^2h$

                            = $\frac{1}{3}\times3.14\times5^2\times2.5$

                            = $65.42\:in^2$

Therefore, Volume of cone is 65.42 in²
