C = 56.549m
The area of the shaded region is 1265.42 meters squared, since I subtracted the two totals of both the unshaded region and the shaded region of a circle.
Circumference = 2*π*r = 56.549 m ( to 3 dp) and Area = π*r2 = 254.469 metres2
Area = 9*6 = 54 square meters

The area of a circle if the radius is 9m 254.5m2
the diameter of a circle with the radius of 9m is 18m
C = 56.549m
The surface area of a cylinder with a radius 2m and 9m height is 138.23m2
The area of the shaded region is 1265.42 meters squared, since I subtracted the two totals of both the unshaded region and the shaded region of a circle.
The area of a circle is its radius squared times pi. The area of your circle (according to a Google search) is 254.4690087
Circumference = 2*π*r = 56.549 m ( to 3 dp) and Area = π*r2 = 254.469 metres2
Circumference = Pi x 18m = 56.5487m (to nearest 4th decimal)
Area = 9*6 = 54 square meters
