A circle has a radius of 40 cm. which of these is closest to it's area
A. 10,053 cm to the power of 2
B. 5,026 cm to the power of 2
C. 251 cm to the power of 2
D. 126 cm to the power of 2
The formula for the area of a circle is given by A = πr^2, where r is the radius of the circle.
Plugging in the given radius of 40 cm into the formula, we get:
A = π(40^2)
= π(1600)
≈ 5026 cm^2
Therefore, the answer closest to the area of the circle is B. 5,026 cm^2.
