Question

If h = 21 units and r = 7 units, what is the volume of the cone shown above?

Use 3.14 for pi
A. 3,231.06 cubic units
B. 1,077.02 cubic units
C. 153.86 cubic units
D. 461.58 cubic units

Answer 1

Option B. 1077.02 cubic units

Explanation:

As we know the formula of cone is
`V = (1)/(3)\pi r^(2)h`

In the given question given dimensions are h = 21 units and r = 7 units.

Therefore we can calculate the volume of the cone with the given dimensions.

`V = (1)/(3)\pi(7)^(2)(21)`

`V=(1)/(3)(3.14)(49)(21)`

V = 3.14×49×7 = 1077.02 cubic unit

So the volume of the given cone is 1077.02 cubic units
