Find the Area circle (6CM)
r=6CMr=6CM
Step 1
The area of a circle is equal to Pi ππ times the radius rr squared.
π(radius)2π(radius)2
Step 2
Substitute in the value of the radius r=6r=6 into the formula for the area of a circle. Pi ππ is approximately equal to 3.143.14.
π62π62
Step 3
Raise 66 to the power of 22.
π36π36
Step 4
Move 3636 to the left of ππ.
