Question

find the circunference of the circle whos radius is
1. 49
2. 56
3.14​

Answer 1

Answer:

Step-by-step explanation:

circumference=2$\pi$r

2x22/7 x49

= 308

2x 22/7 x 56

=352

2 x 22/7 x 14

=88

Answer 2

Answer:

Step-by-step explanation:

Case 1

When r=49

Circumference of circle = 2πr

2*22/7*49

= 308

Case 2

When r=56

Circumference = 2πr

2*22/7*56

= 352

Case 3

When r=14

Circumference = 2πr

= 2*22/7*14

= 88
