Question

A right circular cylinder has a base whose area is 616 square feet. If the height of the cylinder is 13 feet, what is its lateral area? Use π = 22/7

363 ft2

572 ft2

1760 ft2

1144 ft2

Answer 1

Use the area of the base , pi R^2 to get the radius
use 2 pi R to get the circumference
use 2 pi R h to get the lateral area from h = 13 the height

Answer 2

what does R stand for

Answer 3

Answer 4

R = radius of cylinder

Answer 5

how do you get the radius u said area , pi R^2

Answer 6

area = 616 = pi R^2 solve for R

Answer 7

R = sqrt[616/pi]

Answer 8

14

Answer 9

1144

Answer 10

@douglaswinslowcooper

Answer 11

R = 14 yes
2 pi R h = 1144 right also
good

Answer 12

thanks
