Find perimeter of a circle frm whch a circle has been cutt off?

To find the perimeter, you actually need to find the circumference of a circle.

Step-by-step explanation:

The formula to find the circumference is:

C= 2 pi times r

The r is the radius of the circle. The 2 stays the same. If you have the radius then you are fine.

E.g. If you have a circle and you're given that the radius the distance from the center to a point on the circle is 10. Since you have the radius, all you will have to do is C= 2 pi times (10). So 2 times 10 is 20 so it'll be 20 pi for the circumference.

I hope this helped sorry if it's confusing. If you have any questions please ask.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
