The volume of a cylinder is 2,200 pie cubic inches. The diameter of the circular base is 10 inches. What is the height of the cy
Elis [28]

Answer:

Step-by-step explanation:

H = V/ pie r^2

H = \frac{2200pie}{Pie 5^2}

R= 5 because the radius is half the diameter

Pies cancel out leaving you with:

H = 2200/5^2

H = 2200/25

H = 88

Hope this helps :)
