If the volume of the cone is 180 in^{3}, what is its surface area? Use 3.14 for π and round the answer to the nearest hundredth.

The surface area = in^{2}.

V = 1/3 × πr^{2} × h

h = (3 × V) / (π × r^{2}) = (3 × 180) / (3.14 × 25) = 6.88 in

l = = 8.50 in

So, SA = πr^{2} + πrl

= 3.14 × 25 + 3.14 × 5 × 8.50

= 211.95 in^{2}
