Using a compass, Jane draws a circle on her paper with a radius of 2.5 inches. What is the area of the circle?
Responses
A 15.7 15.7 in 2
B 19.625 19.625 in 2
C 24.649 24.649 in 2
D 61.6225
B 19.625 19.625 in 2
To find the area of a circle, you use the formula: A = πr^2. Given that the radius is 2.5 inches, we substitute 2.5 for r in the formula:
A = π * (2.5)^2
A = π * 6.25
A = 19.625
Therefore, the area of the circle is 19.625 in^2.
