Radius is 2.39
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).
Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.
radius = 94.2/(2*pi) = 14.99239564 or about 15 yards
If the radius of a circle is 15 cm, the circumference is: 94.2 cm
Radius is 2.39

A circle with a circumference of 15pi (47.1238898 units) has a radius of: 7.5 units
The radius is 1.27cm
A radius (not raduis) of 15 units implies a circumference of 94 units.
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.
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========
The answer will depend on what 15 dm represents: the radius, diameter or even circumference!
Circumference of a circle = 2*pi*radius or diameter*pi
