Question

Find the surface area of the cone. Round your answer to the nearest hundredth.

A.
193.00 yd2
B.
606.32 yd2
C.
938.29 yd2
D.
6,735.57 yd2

Answer 1

Answer: B, 606.32 yd^2

Surface Area for cone:
πr[r+√(h^2 + r^2)]

Plug in numbers for radius and height:
π(8)[(8)+√((14)^2 + (8)^2)]

Solve equation (or use calculator):
8π(8+√(196+64))
8π(8+√260)
8π(8+16.1)
8π(24.1)
605.7 yd^2 (slightly off of actual answer because of rounding √260)

Answer 2

The answer is B 606.32.
