 # Volume of a torus given R = 20 and r = 10

## Enter both values below

A torus has a major radius (R) of 20
and minor radius (r) of 10.
Calculate Volume and Surface Area V = (πr2)(2πR)

## Plug in r = 10, R = 20

V = (3.1415926535898)(102)(2 * 3.1415926535898)20
V = (3.1415926535898)(100)(6.2831853071796)20
V = (314.15926535898)(125.66370614359)
V = 39478.417604357

## Torus Surface Area Formula

SA = 4 * π2 * R * r

## Plug in r = 10, R = 20

SA = 4 * 3.14159265358982 * 20 * 10
SA = 4 * 9.8696044010894 * 20 * 10
SA = 7895.6835208715

V = 39478.417604357
SA = 7895.6835208715

V = 39478.417604357
SA = 7895.6835208715
