Question

There are many cylinders with a height of 9 inches. Let r represent the radius in

inches and V represent the volume in cubic inches.
Complete the table relating the radius and volume of cylinders with height 9
inches. Round each number to the nearest cubic inch.

IGNORE THE NUMBERS IN THE CHART THEYRE WRONG! THATS WHY IM ASKING BECASUE IM RETAKING

Answer 1

Explanation:

V, r, h are the volume, radius, and height, respectively.

V = πr²h = 9πr²

The only error in your previous answers was that you forgot the π.

if r = 1, V = 9π1² = 9π ≅ 28 in³

if r = 2, V = 9π2² = 36π ≅ 113 in³

if r = 3, V = 9π3² = 81π ≅ 254 in³
