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?
Volume =B.A*height =1/3r2 h
Thus Volume =48ft3 and Height= 4ft
Replacing in the equation
48=1/3r2 4 divide both sides by 4
12=1/3r2 multiply both sides by 3 to remove fraction
36=r2 Divide through by
11.46=r2 into 2d.p.
find the square root both sides
3.39=r into 2d.p.
Therefore, radius r=3.39
