Question

Cameron is replacing the roof on a gazebo. The roof is in the shape of a cone with an open bottom. The diameter is 14 feet and the slant height is 10 feet. What is the lateral area of the roof? Use 3.14 for pi.

Answer 1

Please help...

Answer 2

use the formula

LSA = pi*r*s

where

r = radius
s = slant height

Answer 3

what's LSA

Answer 4

LSA = lateral surface area

Answer 5

in this case

r = 7 (radius = half of the diameter)
s = 10

Answer 6

so my equation would look like this: LSA = 3.14 (7)(10)

Answer 7

yep

Answer 8
