Answer:

12 inches

Explanation:

Given

  • Volume = 763 cubic inches
  • Diameter = 9 inches ⇒ Radius = 9/2 inches

Formula for Volume of a Cylinder

  • V = πr²h

Solving

  • 763 = 3.14 x (9/2)² x h
  • 763 = 3.14 x 81/4 x h
  • 763 = 3.14 x 20.25 x h
  • 763 = 63.585h
  • h = 11.99 ≅ 12 inches

Answer:

The height is 12 inches

Explanation:

Step 1: Determine the knowns a formula


Volume = 764\ in^3


Diameter = 9\ in


Formula: V = \pi r^2h

Step 2: Input the values and solve


V = \pi r^2h


764\ in^3 = \pi (9/2\ in)^2h


764\ in^3 = \pi (20.25\ in^2)h


764\ in^3 =63.617\ in^2 * h


(764\ in^3)/(63.617\ in^2) = (63.617\ in^2 * h)/(63.617\ in^2)


12.0\ in = h

Answer: The height is 12 inches
