Question

Find the volume of cylinder which meet by folding a paper of size 88cm by 48 cm along with length

Answer 1

IF THE CYLINDER IS FOLDED ALONG ITS LENGTH....
THEN THE CIRCUMFERENCE OF THE BASE OF THE CYLINDER WILL BE = THE LENGTH.....
AND THE BREADTH OF THE PAPER WILL BE THE HEIGHT OF THE CYLINDER.....
SO, A/Q;
Circumeference =
$2\pi r \\ = > 88cm = 2 \times \frac{22}{7 } \times r \\ = > \frac{88cm \times 7}{2 \times 22} = r \\ = > r = 14cm$
SO, RADIUS = 14cm
AND HEIGHT = 48cm
SO, VOLUME OF THE CYLINDER =
$\pi {r}^{2} h \\ = \frac{22}{7} \times {(14cm)}^{2} \times 48cm \\ = \frac{22}{7} \times 14cm \times 14cm \times 48cm \\ = (22 \times 14 \times 2 \times 48) {cm}^{3} \\ = 29568 {cm}^{3}$
THERE YOU GO!!!.....
