Answer:
Step-by-step explanation:
Perimeter of square = 4* side
= 4 * 8 = 32 cm
Circumference of circle = Perimeter of square
2πr = 32
2*3.14*r = 32
side length of square = 8
perimeter of square = 4*(side length) = 4*8 = 32
perimeter of square = perimeter of circle = circumference = 32 cm
circumference formula is
C = 2pi*r
32 = 2pi*r .... plug in the given circumference
32/(2pi) = (2pi*r)/(2pi) .... divide both sides by 2pi
16/pi = r
r = 16/pi
r = 16/pi = the exact radius in terms of pi
r = 5.092958 = the approximate value of the radius
The units for the radius are in centimeters.
22 cm
Simply count the number of square units of each side, then add them up. (each square unit = 1 cm)
4+4+2+3+2+7
= 22 cm
A) ÷
