Question

The volume of a cylinder is 471 cm? If the

Answer 1

Answer:

Step-by-step explanation:

Formula for volume of a circle: V=πr²

If you multiply the circle by height, it becomes a cylinder.

Formula for volume of a cylinder: V=πr²h

Plug in the numbers and get r by itself:

471 = πr²(6)

Divide both sides by 6:

78.5 = πr²

Divide both sides by π:

25 = r²

Square root both sides:

$\sqrt{25}$ = $\sqrt{r}$²

5 = r

Radius is 5 cm
