If a cylinder has a height of 10 cm and a radius of 3 cm, what is its total surface area?

Back

SA = 2πr(h + r) = 2π(3)(10 + 3) = 246 cm².

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface of a 3D object, while volume measures the amount of space inside the object.
