R= 4Units
Explanation:
Volume of the cone = 101.06 Cubic Units
Height (h) = 12 Units
Radius (r) = ?
Thus formula, for volume of the cone = 1/3 *πr2h
(Plug in the values and solve for r):
1/3*π*r2* 12 = 201.06
r2*4 *π = 201.06
r2* 12.57 = 201.06
(Divide both steps by 12.57):
r2 = 201.06/12.57
r2 = 15.9952267
r = [15.9952267
r = 4 Units
Hopefully this helps???
