Kaela wrote an equation, y = kx, to model the relationship between the circumference, y, and the diameter, x, of the circle. Which of
the following statements correctly describe what k represents in this equation?

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

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.
