(hint: the formula for the volume of a cone is v = 1 3 πr2h.)

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

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
