Write a cosine function that has an amplitude of 5, a midline of 2 and a period of 7π/5

.

Use the radius you found in part i (r=26.8 cm) with the surface area formula below to find the surface area of the sphere. show your work and round your answer to the nearest tenth. the surface area of a sphere: sa = 4πr^2 self note: 3.8.4

What unit of been sure would be appropriate for the volume of a sphere with a radius of 2 meters
