Question

pie r^2+pierl. plzz factorise this​

Answer 1

answer-πr(r+l)

explanation is in the pic

Answer 2

$\huge{\bold{\red{\underline{\overline{\mid{Solution}\mid}}}}}$

Cone :-

Total Surface Area (T. S. A)

$= > \pi {r}^{2} + \pi \times rl \\ = > \pi \times r(r + l)$

Curved Surface Area (C. S. A)

$= > \pi \times rl$

Volume

$= > \frac{1}{3} \pi {r}^{2} h$

Slant height (l)

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

where,

r = radius

h = height

l = slant height
