Answer:
The height = 18 inches
Step-by-step explanation:
The volume = area of the base × height
Area of the base = 40.5 inches²
The volume = 729 inches³
729 = 40.5 × height
Height = 729 ÷ 40.5 = 18 inches

3x = 60
60 divided by 3 = 20
So the value of x is 20.
Hope it helped! My answer is expert verified.
you use the formula: A=pi*r^2
hopes this helps
2x = 84 so 2x /2 = 84/= x=42
