Question

A company is designing a new cylindrical water bottle. The volume of the bottle will be 100 cmcubed. The height of the water bottle is 8.4 cm. What is the radius of the water​ bottle?

Answer 1

1.95 cm

Explanation:

πr²h is the formula for the volume of a cylinder.

πr²*8.4=100

Divide both sides by 8.4

πr²=11.9047619047619

Divide both sides by π

r²=3.78940340695

`√(3.78940340695)`=r

r is about 1.94663900273 or 1.95cm
