PLEASE HELP ME WITH THIS! ANYONE? HELP Given the perimeter of the whole diagram is 53 cm. Calculate
a) The radius of the quadrant.
b) The area of the whole diagram.

a) 7 cm

b) 185.5 cm^2

Step-by-step explanation:

a)

Let the side of each of the small square be x.

We have 3 squares that have a side of x.

Then we have a quarter circle with x radius.

The perimeter of the entire figure consists of 6 segments of length x and a quarter circumference of a circle with radius x.

perimeter = 6x + 2(pi)x/4

The perimeter = 53 cm

6x + 2(pi)x/4 = 53

7.571x = 53

x = 7

The radius is 7 cm.

b)

The area of the whole figure is the area of 3 squares of side 7 cm plus a quarter circle of radius 7 cm.

area = 3s^2 + (pi)r^2/4

area = 3(7 cm)^2 + (pi)(7 cm)^2/4

area = 147 cm^2 + 38.5 cm^2

area = 185.5 cm^2

The area is 185.5 cm^2

a) 7 cm

b) 185.5 cm^2

Step-by-step explanation:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
