(iv) 56 dm


please give me its answer it is urgent please solve step by step ​

Answer 1

Answer:

The circumference of the circle = 44cm

Step-by-step explanation:

because circumference of the circle=2πr. Therefore 2×22/7×7 = 44 . Therefore the circumference of the circle is=44cm.

Answer 2

Step-by-step explanation:

Let r be the radius of the circle.

Then according to the problem we've r=28.

Then perimeter will be (P)=2πr

P=2×

7

22

×28

P=176 mm.

So the perimeter of the circle is 176 mm.
