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.
A. 615.4 mm2
B. 30,156.6 mm2
C. 9,604 mm2
D. 307.7 mm2
The area of a circle can be calculated using the formula A = πr^2, where A is the area and r is the radius.
Substitute the given radius of 98 millimeters into the formula:
A = 3.14 x (98)^2
A = 3.14 x 9604
A = 30,156.6 mm^2
Therefore, the correct answer is B. 30,156.6 mm^2.
