A wheel has radius 9 cm. What is the area of the circle? Use π ≈ 3.14.

• A. 254.34
• B. 226.08
• C. 203.40
• D. 281.00

Answer: (A)

Area of a circle is π times the radius squared. With a radius of 9 cm, r^2 = 81. Using π ≈ 3.14, the area is 3.14 × 81 = 254.34 square centimeters. So the circle’s area is about 254.34 cm^2.
