Question

the circumfrence of circle is 68.2 cm. find the radius of the circle?
(take pi= 3.14)​

Answer 1

Step-by-step explanation:

Circumference = 2(pi)r

68.2=2×3.14 × r

68.2/6.28 = r

10.85 = r

Answer 2

Answer:

Step-by-step explanation:

Circumference = 2*22/7*radius

68.2=682/10=2*22/7*radius

682*7/10*2*22=radius ( 682÷11 =62 & 22÷11=2 )

31*7/10*2=radius

217/10*2=radius

108.5/10=radius

Radius = 10.85
