In a circle, which ratio is equivalent to π?
A. Radius to Area
B. Diamiter to radius
C. Area to circumference
D. circumference to diameter

A - Radius to Area

π r² is the formula to find the area in a circle

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

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.
