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 :
The curved surface area of the cylinder is given by :
So, the volume is 1386 cm³ and curved surface area is 396 cm².
