The radius of a circle is half the diameter. So if the diameter is 5cm, the radius would be 2.5cm.
Oh, what a happy little question! If the diameter of a circle is 10 cm, we can find the radius by simply dividing the diameter by 2. So, the radius would be 5 cm. Just imagine that circle sitting there, perfectly balanced and ready for some happy little trees.

Pi x radius(R) squared e.g radius of circle is 5cm A=3.14x5 squared Area is 78.5
Diameter = 14cm so radius = 7cm. Height = 5cm. Take pi as 22/7 Volume of a cylinder = pi*radius2*height Volume = 22/7*72*5 = 770 cubic cm.
