Question

What is the formula of TSA of a cone

Answer 1

Answer:

πrl + π$r^{2}$

Step-by-step explanation:

πrl refers to the curved surface area of the cone, where r is the radius and 'l' is the slant-height (which can calculate if you know the radius and height by applying pythogoras theorem).

π$r^{2}$ refers to the area of the circular base of a cone

So:

TSA = CSA + π$r^{2}$

$\implies \: tsa \: = \: \pi \: r \: (l + r) \\ \\ \implies \: csa \: = \pi \: r \: l\\ \\ \implies \: volume \: = \frac{1}{3} (\pi \: {r}^{2} h)$
