10 ins = 25.4 cm
0 . 317 litres = 317 cm ³
V = π r ² h
317 = π r ² (25.4)
r ² = 317 / (25.4 π )
r = 2 cm
r = 0.787 inches

From the note you so generously have stated, we are able to find the radius through simple substitutions of the values to their respective variables:
Before continuing however, we have to convert the units of inches to centimeters and liters to milliliters.
1 L = 1000 mL, so, 0.3170 L = 317 mL
1 inch = 2.54 cm, so, 10 inches = 25.4 cm
Since V = (Pi)(r^2)(h), it follows that,
317 = (3.14)(r^2)(25.4)
we now have to solve for r,
317/(3.14)(25.4) = r^2
[317/(3.14)(25.4)]^1/2 = r
For easier computation, I advice you to use a certain tool called a calculator with which you will be able to arrive at the approximated 0.997centimeters.

v=pi r^2 *h
0.3170 = pi r^2 * .254 (1m=39.37 inch, 10 in = .254m)
r^2 = .3170/(pi .254)
r^2 = .397260
r= .63 m

.7270L
.7270 m^3
.7270 m^3 * 35.3 ft^3/m^3 = 26.6 ft^3
26.6 ft^3 * 1728 in^3/ft^3 = 45964.8 in^3
3.14* r^2 * 10 in = 45964.8 in^3
3.14* r^2 = 4596.5 in^2
r^2 = 1463.8 in^2
r = 38.3 in
