The circumference of an 8-inch circle is: 25.1 inches.
Circumference = 50 pi. Length of arc = 50 pi x 35/360 = 175 pi/36 ie close to 15.27 inches.
The diameter of a circle is twice the length of its radius. Therefore, if the radius is 25 cm, the diameter would be 2 x 25 cm = 50 cm. The diameter is a straight line passing through the center of the circle and connecting two points on the circle's circumference.
Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
78.54 yards
