A diameter of a circle has endpoints with coordinates (2,6) and (−4,10).
Find the coordinates of the center of the circle.

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

1foot = 12 inches; 1 yard = 3 feet
