Question

A sphere of diameter 3.0cm is mounted into a thin uniform 0.2mm calculate the length of wire in metres

Answer 1

45000cm

Step-by-step explanation:

volume of sphere= volume of cylanders wire

4/3^2 x 22/7^11 x 15/10^5 x 15/10 x 15/10 = 22/7^2 x 0.1/10 x 0.1/10 x h

---> 2 x 15 x 15/ 0.1 x 0.1 = h

---> h = 450 x 10 x 10

=

45000cm
