and minor radius (r) of 10
Calculate Volume and Surface Area
Torus Image
Torus Volume Formula
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
SA = 7895.6835208715
