The japanese 5 yen coin has a hole in the middle. if the diameter of the coin is 22 mm and the diameter of the hole is 5 mm, how would you calculate in terms of es002-1.jpg how much longer the outer edge is than the inner edge?

answer:      

step-by-step explanation:

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.
