Sphere volume & surface

(4/3)πr³ and 4πr² — Archimedes worked these out without calculus.

Archimedes worked out the volume and surface of a sphere two thousand years before calculus.

Try this

radius r

volume = 4/3·π·r³ = 523.6

Try this

radius r

surface area = 4·π·r² = 314.16

Volume

V = (4/3) π r^{3}

Surface area

A = 4 π r^{2}
