Acircular patio has a diameter of 35 yards . what is the circumference of the patio? use 22/7 for pie

If the patio has a diameter of 35, then its radius is 35/2.

Circumference of a circle is given by C = 2 * pi * r

 C = 2 * 22/7 * 35/2

C = 110 yards

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.
