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 |
