A cylindrical shaped speaker of circumference 44 cm is wrapped around by a piece of paper of area 528 sq.cm. Find the volume of the speaker in cubic meters.1). 0.000772). 0.000963). 0.001284). 0.00225

Answer»

Given,

The circumference of SPEAKER = 44 cm

⇒ 2πr = 44

⇒ r = 7

Total surface AREA of cylinder = 2πr(H + r)

⇒ 2πr(h + r) = 528

⇒ h = 5

Now,

We know that,

Volume of cylinder = πr2h = (22 × 7 × 7 × 5)/(7 × 100 × 100 × 100) = 0.00077 m3
