Question

the radius and height of a metallic cylinder are 4.2 cm and 5.6 CM respectively it is melted and recast into a square find the radius of the sphere ​

Answer 1

Answer:

Let the radius of the cylinder be R and sphere be r

Step-by-step explanation:

vol of cylinder = vol of sphere

π×4.2×4.2×5.6 = 4÷3×π×r3

98.784×3÷4 = r3

74.088 = r3

therefore r = 4.2 cm
