No. If you use the formula C=2(pi)(r) This mean you multiply pi=3.14 as an approximation ( if you want to find what pi equals for the question then go ahead and find both the diameter and circumference then divide the diameter by the circumference and that's what you use for pi for that problem) OK back to the question you multiply pi by 2 ( use 3.14 for pi) then once you get the product of pi times 2 then you multiply that by your radius. That's what that means. Hope you understand it if not just ask me and I'll try to explain in another way. (:

What is the height of a cylinder when only given the volume and radius?
Since the formula for the volume of a cylinder is PI time the radius squared times the height we can calculate the height from the other two values. The height is the volume divide by PI times the radius squared.
How do you work out the piremeter of a circle?
You mean circumference. It is pi multiplied by radius squared. So whatever the radius is times itself (or "squared") times 3.14 (pi). If the diameter is given, divide by 2 to get the radius and times the radius by itself. For example: diameter=10 radius=5 5x5=25 25x3.14=78.5... The circumference of the circle is 78.5 and then the units of measurement
What value should you get if you divide the area of any circle by the square of its radius?
You will get pi since area of a circle equals pi* times radius squared....by Mona Martinez
What is the area of a circle with a 3.35 in diameter?
Area of a circle is pi x radius squared. Diameter is radius times 2. To get radius just divide the diameter by 2. 3.35 divided by 2 is 1.675. Pi x 1.675 squared is approximately 8.81413.
What is the area of a circle radius equal to 1?
The area of a circle is pi times (radius squared) Thus if radius is one inch then area is (pi) times (1) times (1) = pi = 3.1416 inches squared
