Question

7. What is the surface are of a conical grain storage tank that has a height of 37 meters and a diameter of 16 meters? Round the answer to the nearest square meter.

2,831 square meters
2,664 square meters
1,152 square meters
1,131 square meters

Answer 1

let the slant height be s
s^2 = 8^2 + 37^2
s = 37.8549..

Lateral surface area = πrs
= π(8)(37.8549..)
= appr 9514 , none of the given choices

if we include the circular base of 201.062

we get appr 1152 m^2

Answer 2
