A cylinder with base radius of 8 cm and height of 2 cm is melted to form a cone of height 6 cm. Find the radius of the cone?A4 cmB6 cmC8 cmD5 cmAnswer: C. 8 cm Read Explanation: volume of cylinder = πr²h r = 8 h = 2 volume of cylinder = πr²h = π ×64 × 2 = 128π volume of cone = πr²h/3 = π × r² × 6/3 volume of cylinder = volume of cone π × r² × 6/3 = 128π r² = 128 × 3/6 = 64 r = 8Read more in App
