Question

The base radius of a cone is 6 cm and its vertical height is 8 cm . What is its slant

height .​

Answer 1

Answer:

Slant height = 10 cm

Explanation:

(slant height)²  = (height)² + (radius)²

                         = 8² + 6²

                         = 64 + 36

 (slant height)² = 100

   slant height   = 10

Answer 2

Answer:

$\bold{ ({slant \: height})^{2} \: = \: ({height})^{2} + ( {radius})^{2} } \\ \bold{({slant \: height})^{2} \: = \: {8}^{2} + {6}^{2} } \\ \bold{({slant \: height})^{2} \: = \: 64 + 36} \\ \bold{({slant \: height})^{2} \: = \: 100} \\ \bold{slant \: height \: = \: \sqrt{100} } \\ \bold \red{slant \: height \: = \: 10cm\: \: \: .....ans}$

hope it helps you....
