Question

Which is closest to the volume of the figure shown below?

7 mi
2 mi
351.9 cubic mi.
Ob
117.3 cubic mi.
Ос
29.3 cubic mi.
Od
7.3 cubic mi.

Answer 1

c. 29.3 cubic mi

Explanation:

Applying,

V = πr²h/3.............. Equation 1

Where V = volume of the cone, r = radius of the circular base, h = height of the cone, π = pie

From the diagram,

Given: h = 7 mi, r = 2 mi

Constant: π = 3.14

Substitute these values into equation 1

V = 3.14(7×2²)/3

V = 29.3 cubic mi

Hence the right answer is c. 29.3 cubic mi
