Answer 2

✬ TSA = 30,800 cm² ✬

Step-by-step explanation:

Given:

• Circumference of base of cylinder is 220 cm.
• Height of cylinder is 105 cm.

To Find:

• What is the total surface area of cylinder ?

Solution: Circumference of base of cylinder is 220 cm i.e

➯ 2πr = 220

➯ 2 x 22/7 x r = 220

➯ r = 220 x 7/44

➯ r = 35 cm

Now, we have Radius = 35 cm & Height = 105 cm. Therefore total surface area :-

★ TSA of Cylinder = 2πr ( h + r ) ★

$\implies{\rm }$ TSA = 2 x 22/7 x 35 ( 105 + 35 ) cm²

$\implies{\rm }$ TSA = 44/7 x 35 ( 140 ) cm²

$\implies{\rm }$ TSA = 44 x 5 x 140 cm²

$\implies{\rm }$ TSA = 30,800 cm²

Hence, the total surface area of cylinder is 30,800 cm².
