Circle A has radius of 4 units. If it takes 10 seconds for one revolution. What is the circumference of circle A?
A.4 ≈ 12.56
B. 8 ≈ 25.12
C. 16 ≈ 50.24
D. 2 ≈ 6.28

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
