radius = 3, height = 15
Answer:
339.3 square units
Cylinder with radius 3 units and height 15 units
Identify the formula for surface area of a cylinder
Calculate lateral surface area
Calculate area of two circles
Add both areas
Final answer
SA = 2πrh + 2πr²
This formula calculates the surface-area of a cylinder.
A cylindrical can with 3 cm radius and 15 cm height needs 339.3 cm² of material
The surface area of a cylinder is a fundamental concept in geometry. Surface area measures the total area of all surfaces of a 3D object, expressed in square units.
By using the formula SA = 2πrh + 2πr², we can quickly and accurately calculate the surface area for any cylinder when we know the required measurements.
