Question

A cone has a radius of 5 inches and a height of 18 inches. What is the exact volume of the cone? A. 150π in3 B. 300π in3 C. 450π in3 D. 540π in3

Answer 1

volume = 1/3 × pi × r^2 × h
= 1/3 × pi × 5^2 × 18
= 150pi

the answer is A

i am a mathematics teacher. if anything to ask please pm me

Answer 2

A.150π

Explanation:

To find the solution to this problem, we will follow the steps below:

First write down the formula for calculating the value of a cone

Volume of a cone = πr²h/3

where r is the radius of the cone and h is the height of the cone.

From the question given, radius= 5 inches and height=18 inches

We can now proceed to substitute our values into the equation;

Volume of a cone = πr²h/3

= π5²18/3

= π×25×6

=150 π

Therefore, the volume of the cone is 150π
