The diameter of circle Z is 5 in. What is its area in terms of pi?
2.5pi squared
5pi squared
6.25pi squared
25pi squared
Please help! I can't figure this out:(
It's 6.25. Ms. Sue is incorrect.
Oh, I figured it out! After the result, divide by pi:)
6.25?
3.14 * 2.5^2 = 19.634...
I'm confused!:( None of those are an option. What am I doing wrong?
The question asks the area in terms of pi.
3.14 * 2.5^2
To find the area of a circle, you need to use the formula A = πr^2, where A is the area and r is the radius of the circle.
In this case, you are given the diameter, which is the distance from one side of the circle to the other passing through its center. The radius is half of the diameter, so the radius of circle Z would be 5/2 = 2.5 inches.
Now, you can plug the radius into the formula to find the area:
A = π(2.5)^2 = π(6.25) = 6.25π
Therefore, the area of circle Z in terms of pi is 6.25π squared.
A = pi * r^2
No.
2.5pi squared
