Our friends, the Egyptians, also had a clever method for calculating the area of a circle. Their method was equivalent to the formula A=(89d)2\displaystyle {A}={\left(\frac{{8}}{{9}}{d}\right)}^{{2}}, where d\displaystyle {d} is the diameter of the circle. Use this Egyptian formula (not our modern formula) to find the following:

A) The area of a circle with diameter of 93.

Answer: Area =
Round your answer to two decimal places (hundredths).

B) The area of a circle with diameter of 72.

Answer: Area =
Round your answer to two decimal places (hundredths).




Note: Can you determine what value of π\displaystyle \pi the Egyptians were essentially adopting? Try it! (This question is not officially part of this problem.)
