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
