Circumference = 2*Ï€*r = 56.549 m ( to 3 dp)
and
Area = π*r2 = 254.469 metres2
Area = pi*r2 = 254.5 sq metres
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 = π x diameter = 9π m ~= 28.3 m
3053.628059
The area of a circle if the radius is 9m 254.5m2
Circumference = Pi x 18m = 56.5487m (to nearest 4th decimal)
Area = pi*r2 = 254.5 sq metres
circumference = {pi} x diameter ~= 3.14 x 9m = 28.26m
Assuming 9m refers to the radius, the diameter is 18 m and the circumference is 56.5 m
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 = π x diameter = 9π m ~= 28.3 m
