The volume of a cylinder is:
where is the radius and is the height.
The height is 4 inches greater that the radius, so:
Substituting this in the formula for volume:
the volume is
thus:
Dividing everything between pi:
We can see that the solution for this is
since
We have the radius, now we find the height:
314 square centimeters
I think it would be 55
Sunil = 10 and Sushil= 40
Present ages-
Sushil= 4x
Sunil= x
5 years ago-
Sushil = 4x - 5
Sunil = x - 5
4x - 5 = 7(x - 5) = 4x - 5 = 7x - 35
= -5 = 3x - 35
= 30 = 3x
= 10 = x
So substitute the xs for 10-
Present Sushil= 4 x 10 = 40
Present Sunil= 10
