Question #171684

The volume of a cone shaped hole is 48 on ft cubes if the hole is 4 feet deep is hat is the radius of the hole?

Expert's answer

Volume =B.A*height =1/3r^{2 }h

Thus Volume =48ft^{3} and Height= 4ft

Replacing in the equation

48=1/3r^{2 }4 divide both sides by 4

12=1/3r^{2} multiply both sides by 3 to remove fraction

36=r^{2} Divide through by

11.46=r^{2} into 2d.p.

find the square root both sides

3.39=r into 2d.p.

Therefore, radius **r=3.39**
