A right circular cone is placed over a cylinder of the same radius. Now the combined structure is painted on all sides. Then they are separated now the ratio of area painted on Cylinder to Cone is 3:1. What is the height of Cylinder if the height of Cone is 4 m and radius is 3 m?
Correct
Answer: B. 6m
Explanation:
Cylinder painted area = 2πrh+πr²
Cone painted area = πrl
2h+r/√ (r² +h1²) = 3:1
h = 6Incorrect
Answer: B. 6m
Explanation:
Cylinder painted area = 2πrh+πr²
Cone painted area = πrl
2h+r/√ (r² +h1²) = 3:1
h = 6 -
