Question

A company is designing a new cylindrical water bottle. The volume of the bottle will be 156156 cmcubed3. The height of the water bottle is 7.37.3 cm. What is the radius of the water​ bottle? Use 3.14 for piπ.

Answer 1

Answer: the radius is 2.61 cm

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

Volume = 156 cm³

Height = 7.3 cm

Therefore,

156 = 3.14 × r² × 7.3

156 = 22.922r²

r² = 156/22.922 = 6.81

Taking square root of both sides of the equation, it becomes

r = 2.61 cm
