Question

Find the Surface Area and Volume of Sphere with radius 12 cm.

Answer 1

The surface area of a sphere is 4 pi R² = 576 pi = 1,809.6 cm² (rounded)

The volume of a sphere is 4/3 pi R³ = 2,304 pi = 7,238.2 cm³ (rounded)

Answer 2

`Radius:r=12cm\\\\Surface\ area:\\A=4\pi r^2\to A=4\pi\cdot12^2=4\pi\cdot144=576\pi\ (cm^2)\\\\Volume:\\V=(4)/(3)\pi r^3\to V=(4)/(3)\pi\cdot12^3=(4)/(3)\pi\cdot1728=4\pi\cdot576=2304\pi\ (cm^3)`
