the formula is PI(3.14)(radius)squared

first is to find the radius they usually give and you like the fullthing so you have to cut it in half like for example the radius is 14 so you cut in half which is 7.next you take 7 and multiply it by itself which is 49.(be sure to NOT multiply 7x2=14)then you multiply everything together.so here it is.(3.14x49)And that's how you find the radius of a circle.(i think....)
