A cylinder has a volume of 288pi cubic meters and a height of 9 meters. what is the area of the base?
1 answer:
Answer:
100.54m²
Step-by-step explanation:
Given parameters:
Volume of the cylinder = 288pi cubic meters = 288πm³
Height of the cylinder = 9m
Unknown parameter:
Area of the base = ?
Solution
To find the unknown which is the base area of the cylinder, we simply use the formula of the volume of a cylinder.
Volume of a cylinder = Base area x height = πr² x h
where π is a constant
r is the radius of the cylinder
h is the height of the cylinder
From here, we make area the subject of the formula:
Base area(πr²) =
Base area = = 32 π = 100.54m²

Remember that the area of a square is just one of its sides squared. 
where
is the area of the square
is one of the sides of the square
Unit square is a square whose sides have length 1, so lets use our formula to find the volume of one unit square:
We now know that each one of the squares has area 1 unit squared. Since there are 28 unit square in our figure, we are going to multiply the area of a unit square by 28 to find the area of our figure:
Area of the figure=
units squared
We can conclude that the area of the figure is 28 units squared.
