Question

find TSA of cylinder whose radius is 2 and height is 6​

Answer 1

Answer:

Radius of cylinder (r) = 2m

Height of cylinder (h) = 6m

Total surface area of cylinder = TSA = 2πr (h + r)

TSA =2πr (h + r) = 2 x π x 2 (6+2)

= 4π (8) = 32π = 100.48m²

∴TSA of cylinder = 100.48m²

Step-by-step explanation:

Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• Here, in this question, we are asked to find the TSA of the cylinder which is the Total Surface Area of the cylinder.
• So, to find the Total Surface Area of the cylinder we must use the formula of :

$\boxed{ \sf TSA \: of \: the \: Cylinder = 2 \pi r (h + r) }$

Here, we have to multiply pi and twice the radius. Then, we have to add the Height and Radius.

Given :

• Radius = 2
• Height = 6

To find :

• TSA of cylinder

Solution :

We know that,

${ \sf TSA \: of \: the \: Cylinder = 2 \pi r (h + r) }$

                             $\sf = 2 \times \dfrac{22}{7} \times 2} \: (6 + 2) }$

                             $\sf = 4 \times \dfrac{22}{7} } \: (6 + 2) }$

                             $\sf = \dfrac{88}{7} \times \: (6 + 2) }$

                             $\sf = 12.5 \times 8$

                             $\sf = 100 \: square \: units$

Therefore, the Total Surface Area of the Cylinder is 100 square units.
