What is the area of a circle with a radius of 2 1/4 meters? Use 3.14 for PI and write the answer in fraction form

The formula for the area of a circle is π * r²

Substituting 3.14 for pi and 2 and 1/4, or 9/4 meters for r:

Area = 3.14 * (9/4) ²

Area = 3.14 * 81/16

Area = 254.34/16 Multiply numerator and denominator by 100/100 to simplify:

Area = 25434/1600 Pull 2 out from numerator/denominator

Area = 12717/800 meters²,

or

15 and 717/800 meters²

It makes very little sense to use 3.14, a decimal number, for pi and then answer in fraction form, but that is one way to write it.
