The volume of a donut-like shape called a torus is given by the formula V = 2╧А┬▓r┬▓R, where r and R are the radii shown and rтЙдR Solve the formula for R
A metal ring in the shape of a torus has a volume of 100 cubic centimeters. Choose three possible values of r, and find the corresponding values of R.

it is probably the graph on the bottom right.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
