Question

A cylinder with radius of 5ft has a volume of 314ft. Find its height

Answer 1

3.9979(depends on what place you need to round to

The equation is V=πr2h. First plug in what you know, 314=π5^2h. 5x5=25 and its multiplied with π. It would look like 314=25πh. Divide the 25π by both sides, leaving your h. Plug it into your calculator.

Check answer:

(I rounded the 4 to the nearest whole number) 4*25*π is approximately 314

Answer 2

4 ft

---------------

Volume of cylinder formula:

• V = πr²h

Given:

• r = 5 ft,
• V = 314 ft³

Find h:

• 314 = 3.14*5²h
• 314 = 3.14*25h
• h = 314/(3.14*25)
• h = 4 ft
