Answer:
r = 4 units
Step-by-step explanation:
Volume of cone = 201.06 cubic units
Height (h) = 12 units
Radius (r) = ?
Thus, formula for volume of cone = ⅓*πr²h
Plug in the values and solve for r
⅓*π*r²*12 = 201.06
r²*4*π = 201.06
r²*12.57 = 201.06
Divide both sides by 12.57
r² = 201.06/12.57
r² = 15.9952267
r = √15.9952267
r ≈ 4 units
