Answer 2

Value of n is 7.

Given:

• if the height of a cylinder is 11cm and
• Area of curved surface is 968sq-cm.
• The radius of the cylinder is (2)n cm.

To find:

• Find n.

Solution:

Formula to be used:

Curved surface area of cylinder

$\bf CSA= 2\pi \: rh$

Step 1:

It is given that

$CSA = 968 \: {cm}^{2}$

height $h = 11 \: cm$

Step 2:

Put the values in the formula.

$968 = 2\pi \: r \times 11$

or

$r = \frac{968 \times 7}{2 \times 22 \times 11}$

or

$\bf r = 14 \: cm$

Step 3:

Find the value of n.

It is given that

$r = 2n$

or

$2n=14$

or

$\bf n = 7$

Thus,

Value of n is 7.
