To begin finding the circumference of a circle you need to know the proper vocab used.
CIRCUMFERENCE-- the distance around a circle DIAMETER-- a line segment that passes through the center of the circle from side to side RADIUS-- a line segment that connects the center of the circle to the circle PI-- the ratio of a circle's circumference C to its diameter d.
use the formula C=2(p)r
To begin write the formula then replace p with 3.14 (do not use the pi button on your caculator!!!) then multiply the whole equation together
or in the event that you have the diameter only divide it by two then find the circumference.
FINDING THE AREA OF A CIRCLE
To find the area A of a circle use the formula A=pr²
REMEMBER THAT p = PI
To begin write the formula then replace pi, then square the radius finally multiply the squared radius by 3.14
