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.
It's 9. (I don't use inches in Canada but I made everything in inches so hopefully it helped)
<h2>
The required number is 18.</h2>
Step-by-step explanation:
Let the required number = x
To find, the required number = ?
According to question,
∴ 2x - 16 - 2 × 10 = 0
⇒ 2x - 16 - 20 = 0
⇒ 2x - 36 = 0
⇒ 2x = 36
⇒ x = 18
∴ The required number = 18
Thus, the required number is 18.
