Answer:
The volume is 1386 cm³ and curved surface area is 396 cm².
Step-by-step explanation:
Given that,
The diameter of a cylinder is 14 cm
Height of the cylinder is 9 cm
We need to find the volume and curved surface area
.
If r is the radius, r = 14/2 = 7 cm
Volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\V=\dfrac{22}{7}\times (7)^2 \times 9\\\\V=1386\ \text{cm}^3[/tex]
The curved surface area of the cylinder is given by :
[tex]A=2\pi r h\\\\A=2\times \dfrac{22}{7}\times 7\times 9\\\\A=396\ \text{cm}^2[/tex]
So, the volume is 1386 cm³ and curved surface area is 396 cm².
