1.	e surface area of a sphere is 1386 cnr. If the sphere is meted and recasted into solid cylinders of radasof 3.5 cm and height 6 cm Cakculate the:(1) radius of the sphere(i) number of cylinders recasted.
Answer» GIVEN,AREA= 1386CM^24πr^2= 1386= r = 10.5cm sovolume=4/3π r^3volume = 4/3 × 22/7× 10.5^3volume = 4851 cm^3.

GIVEN,AREA= 1386CM^24πr^2= 1386= r = 10.5cm

sovolume=4/3π r^3volume = 4/3 × 22/7× 10.5^3volume = 4851 cm^3.
