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 Pi. Round the answer to two decimal places.) 32.71 Inches cubed 65.42 Inches cubed 196.25 Inches cubed 588.75 Inches cubed

Answer 1

32.71 Inches cubed

Explanation:

Let's recall the volume of the cone to be = 1/3πr³h

So using the formula.

r= 5

h = 2.5

I = 3.14

Volume = 1/3 * 3.14 * 5³ * 2.5

Volume = 327.1 in³

Answer 2

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

And replacing we got:

`V = (1)/(3) (3.14) (5in)^2 (2.5in) = 65.42 in^3`

And the best option would be:

65.42 Inches cubed

Explanation:

For this case we have the following info given:

`h =2.5 in` represent the height of the cone

`r = 5 in` represent the radius

And the volume of the cone is given by;

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

And replacing we got:

`V = (1)/(3) (3.14) (5in)^2 (2.5in) = 65.42 in^3`

And the best option would be:

65.42 Inches cubed
