Question

A cylinder with a radius of 5 ft and a height of 11 ft

Answer 1

Note that where you see the word "Pie" you should replace it with its symbol

First find the area of the circle

Area of circle = Pie × Radius²

Area of circle = Pie × 5²

Area of circle = Pie × 25

Area of circle = 78.54ft²

Now multiply the area by the height to find the volume

78.54 × 11 = 863.94ft³

We can approximate this answer to 864ft³
