Question

Find the surface area of a cone with radius 14.2 inches and slant height 24.1 inches.

Answer 1

1708.58658058

Explanation:

Total surface area formula = (π×r²)+(π×r×s)

r = radius

s = slant height

So we substitute the values into the formula (π×r²)+(π×r×s)

(π×14.2²)+(π×14.2×24.1) = 1708.58658058
