Surface area of a cylinders and prisms A cylinder has a diameter of 9cm and a height of 25cm. What is the surface area of the cylinder if it has a top and a base?

Surface area of a cylinder = $2\cdot\pi\cdot r^2$ (area of top and bottom) + $\pi\cdot2r\cdot h$ (r=radius, h=height)
Your cylinder has a radius of $4.5$ cm and a height of 25 cm. Should be simple to plug your values into the formula and solve.
