The figures below are made out of circles, semicircles, quarter circles, and a square. Find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). Chapter Reference a A = cm2, P = cm

Area of the figure = 31.25π cm²

Perimeter of the figure = (12.5π + 10) cm

Step-by-step explanation:

Area of the given figure = Sum of area of the two semicircle + area of a quarter circle

Area of one quarter circle (CDE) =

                                                      =

                                                      = 6.25π

Area of one semicircle = 2 × Area of one quarter circle

                                      = 2(6.25π)

                                      = 12.5π

Area of the given figure = 2×12.5π + 6.25π

                                        = 25π + 6.25π

                                        = 31.25π cm²

Perimeter of the figure = Perimeter of two semicircles + perimeter of one quarter circle + measure of radius DE + measure of radius AB

Perimeter of one semicircle = πr

                                              = 5π cm

Perimeter of one quarter circle = 2.5π

Perimeter of the complete figure = 10π + 2.5π + 5 + 5

                                                       = (12.5π + 10) cm

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
