Question

The curved surface area of a cylinder of height 14cm is 88. The diameter of its circular base is​

Answer 1

the formula for the curved surface area of a cylinder is

CSA=2πrh

r=the radius

h=the height

we have

CSA=88cm2,h=14cm

∴88=2πr×14

r=88 , 28π=227πcm

diameter=d=2×227π

=447π=2.000804999

diameter=2.00cm
