The attached figure shows a cylinder of radius 8 units and height 6 units. We need to find the volume of the cylinder. The formula is as follows :
So, the required volume of the cylinder is .
Let the number of days be x.
138 + 27x = 47 + 40x
40x - 27x = 138 - 47
13x = 91
x = 7
Ans: 7 days
Detailed working:
138 + 27x = 47 + 40x
138 + 27x - 27x = 47 + 40x - 27x
138 = 47 + 13x
138 - 47 = 47 + 13x - 47
91 = 13x
13x = 91
x = 91 ÷ 13
x = 7
6 - 2x = 18
2x = - 12
x = - 6
