Question

Write down all necessary formulas of Cone.​

Answer 1

$\bigstar\:\:\underline{\sf AnsWer :} \bigstar$

Base Area = πr²

Curved surface area = πrl

Total surface area = πr(r+h)

$\sf \bold {Volume }= \frac{1}{3} πr²h$

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

$\sf \: r \: = \sqrt{ {l}^{2} - {h}^{2} }$

$\sf \: h = \sqrt{ {l}^{2} - {r}^{2} }$

Where,

• l = slant height
• h = height
• r = radius
