Sphere

Intersect between plane and a sphere is a circle with a radius of 60 mm. Cone whose base is this circle and whose apex is at the center of the sphere has a height of 34 mm. Calculate the surface area and volume of a sphere.

Correct result:

S =  597.66 cm2
V =  1373.89 cm3

Solution:

r2=602+342=4756 r=68.96 mm S=4πr2=4π4756=597.66 cm2
V=43πr3=43π68.963=1373.89 cm3
