Question 1201741


The lateral area of a cone is 32pi and the slant height is 8. Find the radius, height, total area, and volume.

lateral area = 32 pi
32 pi = pi r^2

r =sqrt(32) = 4 sqrt(2)  ( radius)

Total surface area = pi *r^2 + pi*r*l  l=mslant height)

TSA = pi*32*+pi*16sqrt(2)*8
TSA = 32pi(1+4sqrt(2))
