Question

A company is designing a new cylindrical water

bottle. The volume of the bottle will be 162 cm3.
The height of the water bottle is 7.7 cm. What is
the radius of the water bottle? Use 3.14 for It.

Answer 1

21

Explanation:

To find the area of a cylinder you mutliply radius by height.

r*h = 162

If we know the height is 7.7, substitute it for h.

r*7.7 = 162.

Or:

162 / 7.7

Which gives you 21.03, or 21.
