What is the volume of a cylinder of 8in by 0.5 ft in cubic inches
Naily [24]

The volume of cylinder is 1205.76 cubic inches

<em><u>Solution:</u></em>

We have to find the volume of cylinder

<em><u>The volume of cylinder is given by formula:</u></em>

V = \pi r^2h

Where "r" is the radius and "h" is the height of cylinder

<em><u>Given dimensions are:</u></em>

Radius = 8 inches

Height = 0.5 feet

<em><u>Convert feet to inches</u></em>

1 feet = 12 inches

Therefore,

0.5 feet = 12 x 0.5 = 6 inches

Thus, we have got,

height = 6 inches

<em><u>Substitute r = 8 inches and h = 6 inches in formula:</u></em>

V = 3.14 \times 8^2 \times 6\\\\V = 3.14 \times 64 \times 6\\\\V = 1205.76

Thus volume of cylinder is 1205.76 cubic inches
