Question

A sphere with radius r and a cylinder with radius r and a height of r are shown below. How do the surface areas of these solid figures compare? Which statements are correct? Check all that apply. The surface area of the sphere in terms of r is 4πr2 square units. The surface area of the cylinder in terms of r is 4πr2 square units. The surface area of the cylinder in terms of r is 6πr2 square units. The surface area of the cylinder and sphere are the same. The surface area of the cylinder and sphere are not the same.

    Answer:

    • The surface area of the sphere in terms of r is 4πr^2 square units.
    • The surface area of the cylinder in terms of r is 4πr^2 square units.
    • The surface area of the cylinder and sphere are the same.

    Step-by-step explanation:

    The surface area of the sphere is given by the formula …

      A = 4πr^2

    The surface area of the cylinder is given by the formula …

      A = 2πr^2 +2πrh

    Here, the height (h) is equal to r, so this simplifies to …

      A = 2πr^2 +2πr·r = 4πr^2 . . . . . the same area as the sphere
