Answer 2

Given:

• Radius of cylinder: 3cm
• Height of cylinder: 12 cm

To Find:

• Total Surface Area of cylinder

Formula Used:

T.S.A of cylinder = 2πrh + 2πr

Where,

• π = (default) 22/7
• r = radius of cylinder
• h = height of cylinder

Solution:

This question is given from chapter Mensuration which is proposed to Mathematics in class 8 CBSE. This is a very important chapter for future all classes. Mensuration is the branch of mathematics that studies the measurement of geometric figures and their parameters like length, volume, shape, surface area, lateral surface area, etc.

Here is this question we have got the formula and the values. We only need here to find the T.S.A. So we will put the values in the formula.

T.S.A of cylinder = 2πr (r + h)

☛ T.S.A = 2 × 22/7 × 3 (12 + 3)

☛  T.S.A = 132/7 × 15

☛ T.S.A = 282.85 cm²  

So, the T.S.A of cylinder is 282.85 cm².
