➷ First, you need to find the volume of one tank. Use the Formula to find the volume.

V= 3.14r^2h

V=3.14*25*20

V=1570

Now, you need to find the volume of 4 tanks:

1570 * 4 = 6280 cubic feet of water needed for 4 tanks

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.
