The height of a cone and its base radius are 4 cm and 3 cm respectively. Then its slant height is ……… cm.A) 4 B) 3 C) 5 D) 6 |
|
Answer» Correct option is: C) 5 Given that height of the cone is h = 4 cm and radius of the cone is r = 3 cm. \(\because\) \(l^2 = r^2 + h^2\) = \(3^2+4^2 = 9+ 16 = 25 = 5^2\) \(\because\) l = 5 cm Hence, the slant height of the cone is 5 cm. Correct option is: C) 5 |
