If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches
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
If the radius of a circle is 15 cm, the circumference is: 94.2 cm
A circle with a circumference of 15pi (47.1238898 units) has a radius of: 7.5 units
The answer will depend on what 15 dm represents: the radius, diameter or even circumference!
A circle with a radius of 15 inches has a circumference of: 94.2 inches.
If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches
Circumference = 2*pi*rCircumference = 2*pi(15 inches)= 94 inches========
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.
Radius = 15 / 2 Pi or 2.3873 inches (rounded to 4th decimal).
The circumference is approximately 94.25 inches. (C = 2*Pi*r)
30 pi = roughly 94.25 inches (rounded)
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
If the radius of a circle is 15 cm, the circumference is: 94.2 cm
With a drop all around the edge of 2 inches one can safely add that 2 inches to the radius as if you think of setting the cloth on the floor and the 2 inches would be flatly added. So..., Circumference = 2*pi*r Circumference = 2*pi*(17 inches) = 107 inches =========
