Find the surface area of the cone. Use 3.14 for pi. The radius is 8in and the height is 7in.

Question

need help

Answer 1

the answer is ~ 468

Answer 2

area of sides = pi r L
area of bottom = pi r^2

if the height is 7 and the radius is 8 then the slant height, the hypotenuse
L = sqrt ( 49 +64) = sqrt ( 113 ) = 10.63
the area of the sides is then pi * 8 * 10.63 = 267.2
the area of the bottom is pi *64 = 201.1
the sum = 468.3

Answer 3

Damon is correct!

Answer 4

damon is still right to this day!! thank you guys!! much love stay safe! <3

Answer 5

Do you guys realise that the diameter is 8 which means the radius is 4. And the slant height is 7 not the regular height
