Question

A right cone has a base diameter that is 8 cm and a slant height that is 37 cm.
What is the surface area of the cone?

Answer 1

slant surface area = pi r l
where r=radius
l=slant height

Answer 2

area of base=pi r^2

Answer 3

296pi cm^2?

Answer 4

@sshayer

Answer 5

4/3*pi*r^2

Answer 6

total surface area=pi r^2+pi rl

Answer 7

so 164pi cm^2??

Answer 8

diameter=8
radius=4

Answer 9

148 pi+16 pi=164 pi
you are correct.
