The curved surface area of a right circular cylinder is 176 sq cm and its volume is 1232 cu cm. What is the height of the cylinder ? |

Answer» 2πrh = 176 cm2 & πr2h = 1232 cm3 \(\frac{\pi r^2h}{2\pi rh}=\frac{1232}{176}\) ⇒ r/2 = 7 ⇒ r = 14 cm \(\therefore\) h = \(\frac{176}{2\pi r}\) = \(\frac{176\times7}{2\times 22\times14}\) = 16/8 = 2 cm Hence , height of cylinder is 2 cm. |
