Question

how many solid cylinder of radius 10cm and height 6cm can be made by melting a solid sphere of radius 30cm​

Answer 1

Answer:

180

Step-by-step explanation:

r=30cm

v=

$4\pi {r}^{3} \div 3$

=4×22÷7×30×30×30

=2376000÷7

v of cylinder=

$\pi {r}^{2} h$

=22/7×10×10×6

=13200/7

therefore, no of cylinders =v of sphere/v of cylinder

=2376000/7 ÷ 13200/7

=180
