What is the surface area and volume of the sphere shown below?

Volume of sphere V = 4/3*π*r^3
Now the diameter of the sphere is 18 cm, so r = 18/2 = 9 cm

V = 4/3*π*(9)^3 = 3,053.6 cm^3, or 972 π cm^3

Surface area of a sphere S = 4*π*r^2 = 4*π*(9)^2 = 1,017.9 cm^2 or 324 π cm^2

Some questions are better for google.

SA = 324 × π cm^2 = 1017.8760... cm^2
V = 4/3 π × 729 cm^3 = 3053.6280... cm^3

Surface area: 4*pi*9^2 = 324*pi square cm
Volume: 4/3*pi*9^3 = 972*pi cubic cm

r = d/2 = 18/2 = 9 cm

SA = 4πr^2
SA = 4π(9)^2
SA = 324π cm^2 answer//

solving the volume of a sphere.

V = 4/3πr^3
V = 4/3π(9)^3
V = 972π cm^3 answer//
