Question

The curved surface area of a cylinder is 1320cm and Base has diameter 21cm. find the height and the volume of the cylinder.
​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

CURVED SURFACE AREA OF CYLINDER = 2πrh

1320 = 2×22/7×21/2×h

660 = 22×3/2h

660 = 33h

660/33= h

h= 20cm

VOLUME OF CYLINDER=

$\pi {r}^{2} h$

$volume = \frac{22}{7} \times \frac{21}{2 } \times \frac{21}{2} \times 20$

volume = 6930 cubic centimetre.
