Question

fig 14.5 Nahin hai​

Answer 1

Answer:

Perimeter= 157cm

Radius = 25cm

Diameter = 50cm

Step-by-step explanation:

2$\pi$r= 157

2r=157/$\pi$

2r=157/3.14

2r= diameter= 50cm

Answer 2

Answer:

Step-by-step explanation:

If the length of the wire is 157cm, then the perimeter of the circle made by bending it would become 157cm

2 pi r = 157

r = 78.5/ 3.14

r = 25cm

d = 2r = 50cm
