Question

The first figure given below shows a wire in circular shape with the
radius of 80cm. Shyam cut out an arc from wire such that the arc
makes an angle of at the centre. If this arc is again bent in circular
shapes as shown in the second picture. Find the radius of the new
circle.​

Answer 1

Answer:

Given that:–

radius =80cm

An arc with 90*

Step-by-step explanation:

A/Q

As we know that,

Area of sector =90/360×22/7×80×80=35200/7cm^2

And

we also know that Area of sector =Area of new circle,

35200/7cm^2=22/7.r^2

r^2=35200/7×7/22

r^2=1600

r=40cm

Therefore,the radius of new circle is 40cm

Answer 2

Answer:

40cm okkkkkkkkkkk biography
