Caroline knows the height and required volume of a cone-shaped vase she's designing. Which formula can she use to determine the radius of the vase? Select the correct answer.

Formula for volume of a cone is:

3v = πr²h {multiplied each side by 3}

3V

----- = r² {divided each side by πh}

πh

**V = (1/3)πr²h****Solve for r.**3v = πr²h {multiplied each side by 3}

3V

----- = r² {divided each side by πh}

πh

{took the square root of each side, also the radius cannot be negative}

**B.)**
