Question

circumference of the circle whose diameter is 9.8 metre​

Answer 1

Step-by-step explanation:

d = 9.8 m

then, radius = 4.9

C=2πr

C= 2 x 22 x 4.9

7

C= 30.8

Answer 2

Answer:

diameter = 9.8

r = 9.8/ 2 = 4.9

circumference of circle = 2 pie r

= 2 × 22/ 7 × 4.9

= 2× 22 × 0.7

= 44 ×0.7

= 30.8
