The radius of a circle is 98 millimeters. What is the area of the circle? Use 3.14 for pi and express tour answer to the tenths place. (1 point)
A. 615.4 mm squared
B. 30,156.6 mm squared
C. 9,604 mm squared
D. 307.7 mm squared
A. 615.4 mm squared
To find the area of a circle, you use the formula A = πr^2. Plug in the values given:
A = 3.14 * 98^2
A = 3.14 * 9,604
A ≈ 30,156.6 mm squared
Therefore, rounded to the tenths place, the area of the circle is approximately 30,156.6 mm squared.
