Question

the area of the base of a right circular cylinder is 15400 cm^2.the volume is 92400cm^3.find the area of curved surface.

Answer 1

hello friend!!!

here's ur answer...

given:-

area of the base of the cylinder=15400cm²

πr²=15400cm²

22/7×r²=15400cm²

r²=15400/1×7/22

r²=4900

r=70cm

volume of the cylinder=92400cm³

πr²h=92400cm³

22/7×70×70×h=92400cm³

15400×h=92400cm³

h=92400/15400

h=6cm

CSA of the cylinder=2πrh

=2×22/7×70×6

=44/7×420

=18480/7

=2640cm²

hope this helps u...
