This x=7/3 hope this helps :)
Given dimensions:
Height of the cylinder = 2 m
Volume is increasing at a rate of = 10 m³/min
Radius = 4 inches
Converting radius in meters.
1 inch = 0.0254 meters
4 inches = meters
we have to find,
Volume of the cylinder is given by
=
Now differentiating with respect to 't'
= 7.83 meter per minute.
The expanded form for 15,409 is 10,000 + 5,000 + 400 + 9
