Question

If anyone can help me I'll medal and fan.
Find the diameter of a cone that has a volume of 83.74 cubic inches and a height of 5 inches. Use 3.14 for pi.
3 inches
4 inches
8 inches
16 inches

Answer 1

Anyone?

Answer 2

The volumen of a cone is
1/3h(πr^2)=V
1/3(5)(3.14*r^2)=83.74
(83.74*3)/(5π)=r^2

Answer 3

So now you know the radius, and the diameter is 2r

Answer 4

Would that make it 3?

Answer 5

I get r≈4 so diameter is 2(4)≈ 8

Answer 6

Okay thank you.
