Answer:
What is the surface area of a cylinder that is 25cm high and whose base radius is 8cm
Surface Area of a Cylinder = 2πr²+2πrh
Surface Area of a Cylinder = 2π(8)²+2π(8)(25)
Surface Area of a Cylinder = 2π(64)+2π(200)
Surface Area of a Cylinder = 128π+=400π
Surface Area of a Cylinder = 528π ≈ 1658.76cm →Ans.
Explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape.
