Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)

you double the radius to find the diameter.

Easy, you find the area of the circle (Pi X Radius squared) and then multiply it by the height. Your question asks about using the diameter...the radius is half of the diameter.

the radius is half the diameter

Yes, the radius is half of the diameter, therefore the diameter is twice the radius.
