Question

The radius of a cone is 3cm and
vertical height is 4 cm. Find the area
of the curved surface
(1 Point)
47.14cm2
47.2cm?
47.34cm?​

Answer 1

Answer:

CSA of cone is =π×r×l

slant hight is denoted by=l

$slant \: hight \: of \: cone \: = \sqrt{r ^{2} + h ^{2} }$

radius=3cm

vertical hight =4cm

slant hight= 5cm

CSA of cone=22/7×3×5=47.14cm^2
