4. Find the radius of a circle whose circumference is 57.2 cm.​

Answer 1

Answer:

143/5pi = 9.10366

Step-by-step explanation:

2(pi)r = 57.2

Answer 2

Circumference of a circle=57.2cm

2πr=57.2

2×22/7×r=57.2

r= 57.2×1/2×7/22

r=9.1000000005cm

r=9.1cm(approx)

Hence, the radius of the circle is 9.1cm
