Question

A

Answer 1

lateral surface area = 2*pi*r*h
radius is not given so you need to find it first.
area = pi*(r^2)
radius = \(\sqrt{area/pi}\)
radius = \(\sqrt{616/pi}\)

Answer 2

it says that pi is 22/7 so radius = \(\sqrt{616/(22/7)}\)

Answer 3

what is the radius?

Answer 4

yes 14 is right

Answer 5

now substitute it. lateral surface area = 2*22/7 * 14 *13

Answer 6

1144 is correct

Answer 7

you're welcome :D
