The radius of a circle is 98 millimeters. What is the area of the circle? Use 3.14 for PI and express your answer to the tenths place.
615.4 mm2
30,156.6 mm2
9,604 mm2
307.7 mm2
The area of a circle is given by the formula A = πr^2. Plugging in the values:
A = 3.14 * (98)^2
A = 3.14 * 9604
A = 30156.6 mm^2
Therefore, the area of the circle is 30,156.6 mm^2.
