A lunette is a semi-circle, which means that it is one half of a circle. To find its area, we can find the area of the whole circle and divide it by two.
Area of a circle: A = pi x r^2
r = 40 / 2 = 20
A = pi x 20^2
A = 400pi / 2 = 200pi
200pi = 628.32
The area of the lunette is approximately 628 in^2.
Hope this helps!! :)
1, 3, 5, 7, 9. You could continue on with this pattern forever by adding two to each previous number and it would average out correctly.
2 and 4 are both factors of 8, which means any multiple of 8 can be divided by both 2 and 4 since 8 can be. So, Jose and Jamila are both right.
