Tsa of cylinder 220 cm². Height=6.5 cm find its volume?
Calculation of Volume of Cylinder with Given Surface Area and Height
Given:
- Surface area of cylinder = 220 cm²
- Height of cylinder = 6.5 cm
Formula to Calculate Volume of Cylinder
The formula to calculate the volume of a cylinder is:
V = πr²h
where V is the volume, r is the radius of the base, and h is the height of the cylinder.
Calculation of Radius of Cylinder
We can calculate the radius of the cylinder using the formula for the surface area of a cylinder:
A = 2πrh + 2πr²
where A is the surface area, r is the radius, and h is the height.
Substituting the given values, we get:
220 = 2πr(6.5) + 2πr²
Simplifying the equation, we get:
110 = πr(6.5 + r)
Dividing both sides by π, we get:
35.026 = r(6.5 + r)
Using the quadratic formula, we get:
r = 4.04 cm or -10.54 cm
Since radius cannot be negative, we take r = 4.04 cm.
Calculation of Volume of Cylinder
Now that we have the radius, we can use the formula for the volume of a cylinder to find the volume:
V = πr²h
Substituting the given values, we get:
V = π(4.04)²(6.5)
V = 532.67 cm³
Therefore, the volume of the cylinder is 532.67 cm³.
