Question

A tent has a base that is 20ft. across and a slant height of 14ft. To the nearest whole unit, what is the area of the tent , including the floor. use 3.14 for p

Answer 1

Surface area of a cone = pi * r * s + pi * r^2

pi = 3.14
r = d/2 = 20/2 = 10
s = 14

SA = 3.14 * 10 * 14 + 3.14 * 10^2
SA = 439.6 + 314
SA = 753.6 = 754 sq ft
