Area of circle = p x ( radius x radius ) = p radius2
if the Radius = R
then
Area of circle = pR2 = p x R x R

Area = pi * radius squared
You may be able to substitute pi for 3.14.
An easy way to remember this formula is to think:
pie are squared. (pi) (r) (squared)

Area = pi times radius^2
You might need to use 3.14 for pi. It depends on your teacher.
Good luck.
