What is the circumference of a tire with a radius of 22 centimeters

Step-by-step explanation:

circumference= 2πr

                        = 2**22

                        = 44*

                       = 968/7

                        = 138.28 cm

Circumference of the Tire is  

Step-by-step explanation:

Circumference of any figure is the total length of its boundaries.

Considering the tire as a circle.

Given:

         radius of the tire=

    circumference of a circle =

So, the circumference of the Tire is  

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.

the monthly balance will be $75,000
