# Question #9ab18

##### 1 Answer

#### Answer:

#### Explanation:

Let the radius of the right circular cylinder be **r** *cm*

and height be **h** *cm*

The area of its *Curved Surface* =

The area of its *Plane Crcular Surface* =

So The area of its *Total Surface* =

By the **1st condition** of the problem:

The ratio of total surface area to the curved surface area of a right circular cylinder is 3 : 2

Hence

Now by the **2nd condition** of the problem:

Total surface area = 14784 cm^2

So

**putting h=2r** ]

Hence **Radius of the Cylinder** = r=28 cm

So its height

and **Volume of the Cylinder** =
