A circle with a radius of 15 inches has a circumference of: 94.2 inches.
The radius of a circle with an area of 706.50 square inches is: 15 inches.
Radius = 15 / 2 Pi or 2.3873 inches (rounded to 4th decimal).
30 inches
15 inches.
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
Circumference = Pi multiplied by the diameter. C = (3.1415)(15 in.) = 47.12 in. Therefore, the circumference of a circle with a diameter of 15 in. and a radius of 7.5 in. is approximately 47.12 inches.
The radius of a circle is half the diameter, thus your measurement is 30 inches
30 pi = roughly 94.25 inches (rounded)
The circumference is approximately 94.25 inches. (C = 2*Pi*r)
Area = pi*152 = 706.858 square inches to 3 d.p.
Use Circumference = 2 x radius x Pi Pi is 3.14159 appx. Therefore the circumference of your circle is 2 X 15 X 3.14159 inches or 94.25 inches or 7 feet 10 and 1 quarter inches
