Question

The curved surface area of cylinder of height 14cm is 88cmsquare. Find the diameter of its circle base.

Answer 1

hey the answer is ....

h = 14cm

CSA = 88cm ^2

csa = 2 pi r h

88 = 2 × 22/7 × r × 14

88 = 88 × r

r = 88/88 = 1cm


diameter = 2cm



hope it helps uu frnd

Answer 2

$csa \: of \: cylinder = 2\pi \times r \times h \\ \\ 88cm = 2 \times \frac{22}{7} \times r \times 14 \\ 88cm = 2 \times 22 \times 2 \times r \\ \\ 88 = 88r \\ \\ r = 1cm \\ \\ d = 2r \\ \\ d = 2(1) \\ \\ d = 2cm$
