Answer 2

Answer:

Answer:

• Total surface area=754.3cm²

Given:

• Volume of cylinder=1408cm³
• Height of cylinder=7cm

To find:

• Total surface area of cylinder=?

Solution:

As we know that,

Volume of cylinder=πr²h

→ πr²h=1408

→ 22/7×r²×7=1408

→ 22r²=1408

→ r²=64

→ r=8cm

So, Radius of cylinder=8cm

Now Total surface area of cylinder,

TSA=2πr(r+h)

→ 2×22/7×8(15)

→ 44/7(120)

→ 754.3cm²

So, Total surface area of cylinder=754.3cm².
