The radius is half the diameter. Draw a line that passes through the centre of the circle and measure it. This is the diameter. Halve it and you will have the radius.
Uisng the lateral area and tha radius, you should be able to find the height of the cone. Using the height and radius as the legs of a right triangle, use the Pythagorean Theorem. The hypotenuse is the slant height.
Find the radius of the circle (if it gives you the diameter just half it to get the radius) and then square it. Then times your answer by pie. So the formula is: A= pie (r squared) P.S. Sorry I couldn't get the mathematical symbols!
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
you double the radius to find the diameter.
squares do not have a radius
The radius is 1.27

Assuming you know the radius or diameter...(Pi) x (radius) x (radius) or (1/4 Pi) x (diameter) x (diameter) will give you the area.

you double the radius to find the diameter.
2*22/7*R kis pagal ko nahi aata tha.......
squares do not have a radius
A kite does not have a radius.
You already know the radius.
circumference = pi * 2radius (diameter) so to find radius you use circumference/(2 x pi) this will find radius ----
I guess you mean:"How do you find the radius if you are given the diameter?"You take the diameter and divide it by 2.
