What is the circumference of 15 inch pipe to the nearest tenth?
pi*D So pi*15 here. If you've a scientific calculator (or set the calculator probably in your computer in "Accessories" somewhere, to 'Scientific'), it will have a pi key. But do you mean the circumference of the 15" dimension or is that pipe bore but you want the outside circumference? If the latter you'd need its outside diameter - there will be an appreciable difference!
If the radius is 15 cm what is the circumference?
If the radius of a circle is 15 cm, the circumference is: 94.2 cm
What is the circumference of 15dm?
The answer will depend on what 15 dm represents: the radius, diameter or even circumference!
What is the radius if the circumference is 15 pi?
A circle with a circumference of 15pi (47.1238898 units) has a radius of: 7.5 units
What is the diameter if the circumference is 15 inches with a radius of 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
