Question

A torus is essentially a tube wrapped into a circle​ (a "doughnut"​ shape). The volume​ (V) of a torus can be calculated by

V=2pi^2Rr^2

where R is the radius of the torus​ (from the center of the​ "tube" to the center of the hole in the​ middle) and r is the radius of the tube itself. If a torus has a volume of

2,537

cubic inches

​[in cubedin3​]

with a torus radius​ (R) of

0.26

meters​ [m], what is the radius of the tube​(r) in units of centimeters​ [cm]?
