A square patio measures 16 feet on each side and has a circular fountain of radius 3 feet at its center. Using 3.14 for pi, about how much patio area is not covered by the fountain?

Correct answer to question 233 (Arithmetic Reasoning): 227.7 square feet

Method

Find the full patio area, then subtract the fountain's area. The patio is 16 x 16 = 256 square feet and the fountain is 3.14 x 3 x 3, about 28.3 square feet, leaving about 227.7 square feet of open patio.
