10. A company is designing a new cylindrical water bottle. The volume
ValentinkaMS [17]

The radius of the water bottle to the nearest hundredth is 2.01 cm

<h3>How to calculate the volume of a cylinder</h3>

A cylinder is a solid figure with circular bases and height.

The volume of a cylinder = πr²h

h is the height  = 8.1cm

Volume = 103 cubic cm

Substitute into the formula to have
V = 3.14r² * 8.1
103 = 3.144 * 8.1 * r²

r = 2.01 cm

Hence the radius of the water bottle to the nearest hundredth is 2.01 cm
