Answer:
Given that the curved surface area is 250 cm² and the height is 12 m, we need to convert the height to centimeters for consistency.
1 meter = 100 centimeters
Height of the cylinder in centimeters = 12 m * 100 cm/m = 1200 cm
Substituting the known values into the formula:
250 cm² = 2πr * 1200 cm
Dividing both sides of the equation by 2π * 1200 cm:
250 cm² / (2π * 1200 cm) = r
Simplifying:
r ≈ 250 cm² / (2π * 1200 cm)
r ≈ 0.0331 cm
Now that we have the radius (r = 0.0331 cm) and the height (h = 1200 cm), we can calculate the volume of the cylinder using the formula:
Volume = πr²h
Substituting the known values:
Volume = π * (0.0331 cm)² * 1200 cm
Calculating this:
Volume ≈ 0.0331 cm * 0.0331 cm * 1200 cm * π
Volume ≈ 1.34 cm³ * 1200 cm * π
Volume ≈ 1608 cm³ * π
Volume ≈ 5056.67 cm³
Therefore, the volume of the cylinder is approximately 5056.67 cm³.
