The area of a circle is 44 mm. What is the area of the circle? Use 3.14
A. 138.16 mm squared
B. 276.32 mm squared
C. 4760. 25 mm squared
D. 6079.04 mm squared
A. 138.16 mm squared
To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle.
Given the area of 44 mm, we can set up the equation as follows:
44 = 3.14r^2
Divide both sides by 3.14:
r^2 = 14
Taking the square root of both sides:
r = √14
Now, plug the value of r back into the formula to find the area:
A = 3.14(√14)^2
A = 3.14(14)
A = 43.96
Therefore, the area of the circle is approximately 43.96 mm squared, which is closest to option A.
