Answer: 3 inches

Explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cone = 1/3 x π x radius^2 x height

Replacing with the values given:

75 = 1/3(3.14) r^2 (6)

Solving for r:

75 / (1/3 (3.14) 6) = r^2

75/ 6.28 = r^2

11.94 = r^2

√11.94 =r

3.45 inches = r

3 inches = r
