Question

A cylindrical glass holds 3768 cubic centimeters of water. It has a height of 12 cm. Find the radius.

Answer 1

The radius of the cylinder is

10cm

Explanation:

This problem bothers on the mensuration of solid shapes. A cylindrical shape time

Data given

Volume of cylinder v= 3768cm³

Height of cylinder h= 12cm

We know that the volume of a cylinder is given as

v= πr²h

Taking π=3.142

Substituting our given data and solving for the radius r we have

3768=3.142*r²*12

3768=37.704*r²

r²=3768/37.704

r²=99.94

r=√99.94

r= 9.99

≈r =10cm

Answer 2

Answer: radius = 10 cm.

Explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cylinder = π r² h

Where:

r = radius

h = height

Replacing with the values given:

3768 =π r² 12

Solving for r

3768/ (12π) = r²

99.95 = r²

√99.95 = r

r = 9.99 ≅ 10 cm (rounded)
