The circumferecne of a circle with diameter d is pi*d So diameter = circumference / pi = 36/pi = 11.46 inches. Radius = diameter/2 = 5.73 inches.

A circle with a radius of 18 inches has a circumference of 113.097 inches.

Circumference = 2 x pi x radius = pi x diameter where pi = 3.1416 Diameter = circumference / pi = 36/3.1416 = 11.46

Area of the circle: pi*6 squared = 36*pi square inches

The radius is 18 inches (r = d/2).

Divide the circumference of a circle by pi to obtain the diameter. Diameter of a 36 inch diameter circle is 36/3.1416 inches , or 11.459 inches.

The circumference of the circle is larger than the perimeter of the rectangle.

The circumferecne of a circle with diameter d is pi*d So diameter = circumference / pi = 36/pi = 11.46 inches. Radius = diameter/2 = 5.73 inches.

A circle with a radius of 18 inches has a circumference of 113.097 inches.

Consider the straight side as the diameter of a circle, find the circumference of the circle, calculate half the circumference and then add it to the diameter. circumference = pi x diameter = 3.14 x 36 = 113.04 perimeter of semicircle = 1/2 circumference + 36 = 56.52 + 36 = 92.52

Diameter = twice the radius = 2 x 18 = 36 inches.

Circumference = 2 x pi x radius = pi x diameter where pi = 3.1416 Diameter = circumference / pi = 36/3.1416 = 11.46

The circumference is: 36*pi = 113.097 inches rounded to three decimal places

R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"

The perimeter or circumference of a circle is pi x diameter where pi = 3.1416 The circumference of a 12 inch circle is 3.1416 x 12 = 37.699 inches so two 36 inch lengths will be required.
