Question

how many solid cylinder of radius 5cm and height 3cm can be made by melting a solid sphere of radius 30cm?

Answer 1

Answer:

solid cylinder can be made = 480

Step-by-step explanation:

given:- radius of a solid sphere = 30

           make a solid cylinder of radius 5 cm and height = 3 cm

volume of a sphere = volume of a no of solid cylinder can be made

4/3πr^3  =  πr^2h

4/3×22/7×30×30×30 = 22/7×5×5×3×no of solid cylinder

4×22/7×9000 = 22/7×75×no of solid cylinder

4×22×1285.71 = 1650/7×no of solid cylinder

5142.85×22 = 235.71×no of solid cylinder

113142.85 = 235.71×no of solid cylinder

no of solid cylinder = 113142.85/235.71

no of solid cylinder = 480.008

no of solid cylinder can be made are 480
