Answer:

r = 4 units

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
