Answer:

Step-by-step explanation:
Volume of cylinder is given as
V is the volume the cylinder, r is its radius at the base, while is its height.
To select the formula for h (height) let's make h the subject of the formula as follows:
(dividing both sides of the equation by
)
Use the formula above to find the height of the given cylinder where Volume (V) = 36π cm³, and base radius (r) = 3 cm:
(substitution)
(

Answer:
44 words
Step-by-step explanation:
Step one:
given data
The dimension is
7cm long and = 0.07mm
5mm in diameter
radius= 2.5mm
The volume = πr^2h
Volume= 3.142*2.5^2*0.07
Volume= 3.142*6.25*0.07
volume= 1.4 mm^3
If 1.4 mm^3 will write 310 words on an average
1/5(0.2mm^3) liter will write x
cross multiply we have
x= 0.2*310/1.4
x=62/1.4
x=44 words
