To determine the area if the circle, you must know the diameter or the radius of a circle.
If you know the radius of a circle, use this as your formula. Remember: Pi (the greek symbol thingy) is equal to 3.1415. (A is equal to area of the circle and r represents the radius)

If you know the diameter, just divide the diameter to get the radius then use the same equation.
Answer:
√9/√13=5
√10-3r=r
Step-by-step explanation:
this must be the answer
Answer:
2.25π square inches
Step-by-step explanation:
Area = π
Diameter = 2r
So in this case, radius = 1.5 inches
Plugging that into the area formula produces the answer
