Torus

Torus Volume Formula

V = (πr²)(2πR)

Plug in r = , R =

V = (3.1415926535898)(²)(2 * 3.1415926535898)

V = (3.1415926535898)(0)(6.2831853071796)

V = (0)(0)

V = 0

Torus Surface Area Formula

SA = 4 * π² * R * r

Plug in r = , R =

SA = 4 * 3.1415926535898² * *

SA = 4 * 9.8696044010894 * *

SA = 0

V = 0
SA = 0

What is the Answer?

V = 0
SA = 0
