Question

The volume of a cylinder is 1,386 m^3 and its radius is 7 m. What is its height to the nearest whole number? (Pie = 3.14)

198 m

7 m

9 m

14 m

Answer 1

9m

Explanation:

Formula for the volume of a cylinder is given as πr²h

The volume of the cylinder is 1,386 m^3

radius is 7 m.

π = 3.14

So

1386 = 3.14*7² *h

1386 = 3.14*49*h

1386 = 153.86*h

1386/153.86 = h

9.008 m = h

To the nearest whole number = 9m
