Question

find csa of cone whose sides 12 cmand base radius 5cm​

Answer 1

If by sides you mean ‘l’ then csa is pi * r * l.
Csa = 174.2 cm square

Answer 2

Answer:

given that

base of cone =12cm

radius of cone =5 cm

find= csa of cone

csa of cone =πrl

here r=5 cm ; and the length of cone is =5 cm

now put slant formula =√r^+h^

√ 5*5+12*12=√25+144=√169

=13

here l=13

now put the values in formula =csa

πrl=3.14*5*13

204.1 sq cm
