Question

the curved surface of area of a cylinder is 1320 CM square and its base has a radius of 10.5 cm find the height of the cylinder​

Answer 1

Given :

⬤ Curved Surface Area of Cylinder is 1320 cm² .

⬤ Radius of the Cylinder is 10.5 cm.

To Find :

⬤ Height of the Cylinder .

Formula Used :

$\bf[\:{Curved\: Surface\:Area\:of\:Cylinder=2\pi{r}h}\:]$

• r = radius
• h = height

Solution :

• C.S.A of Cylinder = 1320 cm².
• Radius of Cylinder = 10.5 cm.

According to the Formula :-

1320 = 2πrh

1320 = 2 × 22/7 × 10.5 × h

1320 × 10 = 44h × 15

13200 = 660h

13200/660 = h

20 = h

Therefore , The Height of the Cylinder is 20 cm .

• TotalSurface Area of Cylinder = 2πr (r + h)
• Volume of Cylinder = πr²h
• Total Surface Area of Cube = 6a²
• Volume of a Cube = a³
