Answer is 60.05cm^2
First, find the area of both circular sides:
Area = pi x radius^2
Area = pi x (4.5/2)^2
Area = 15.904....
There are two sides, so times the area of the circle by 2.
15.904... x 2 = 31.808....
Afterwards, find the area of the outside circular part.
You use the formula to find the circumference of the circle as that is just the outside length of the circle.
Circumference = pi x diameter
C = pi x 4.5
C = 4.5pi
Afterwards, times the circumference by the 2cm length.
4.5pi x 2 = 9pi
Then, add up all the area.
31.808 + 9pi = 60.082... approx, where this answer is closest to the last answer.
