Please answer the first question

Answer 1

Answer:

12 inches

Step-by-step 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 2

Answer:

The height is 12 inches

Step-by-step 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

$V = \pi r^2h$

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

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

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

$\frac{764\ in^3}{63.617\ in^2} = \frac{63.617\ in^2 * h}{63.617\ in^2}$

$12.0\ in = h$

Answer: The height is 12 inches
