Question

the CSA of cone is 88m square if the slant height is 7cm then find the vertical height of cone ​

Answer 1

Step-by-step explanation:

$\huge{\underline{\underline{\bold{Question}}}}$

• The CSA of cone is 88m square if the slant height is 7cm then find the vertical height of cone

$\huge{\underline{\underline\bold{Given}}}$

• CSA=88m
• Slant height=7cm

$\huge{\underline{\underline{\bold{Process}}}}$

$CSA = \pi rl= 88m$

$\frac{22}{7} \times r\times slantheight(or \:l)= 88 \\ \frac{22}{7} \times r \times 7 = 88 \\ r = 4m$

$l = \sqrt{r^2 + h^2}$

$7 = \sqrt{4^2 + h^2} \\ 49 = 16 + h^2 \\ h = \sqrt{33}$
