Question

The height of a right Circuler Cylinder
5cm and the area of its bas is 36cm.
Find the Curved surface area of the Glinder​

Answer 1

Answer:

height of cylinder =5cm

circumference =36cm

2 *22/7 *r = 36

r= 63/11

curved surface area of cylinder = 2*22/7*63/11*5

=180 cm2

Answer 2

Answer:

$\pi {r}^{2} = 36 \\ = > \frac{22}{7} \times {r}^{2} = 36 \\ => {r}^{2} = \frac{36 \times 7}{22} \\ = > {r}^{2} = \frac{252}{22} \\ = > r = \sqrt{ \frac{252}{22} }$

CSA=2πrh

$2 \times \frac{22}{7} \times \sqrt{ \frac{252}{22} } \times 5 \\ \frac{220}{7} \times \sqrt{ \frac{7}{\pi} } \: {cm}^{2}$
