Question

A company is designing a new cylindrical water bottle. The volume of the bottle will be 147 cm ^ 3. The height of tbe water bottle is 7.5 cm. What is the radius of the bottle? Use 3.14 for pi

Answer 1

2.496cm

Explanation:

Volume of the cylindrical water bottle. Can be calculated with the equation below

V=πr^2h

Where

h= height

r= radius

Then substitute the values into the equation we have

147= 3.14 × r^2 × 7.5

147= 23.565 r^2

Make r^2 subject of the formula

r^2= 147/ 23.565

r^2= 6.23

r= √6.23

r= 2.496cm
