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
