Question

If the radius of a cone is 60 cm and its CSAis 23.55m^2then Find slant height. (
$\pi = 3.14$



​

Answer 1

Answer:

CSA of cone=πrl

where, r=60cm=0.60m

CSA=23.55m^2

CSA of cone=πrl

23.55=3.14*0.60*l

23.55=1.88*l

23.55/1.884=l

12.5=l

Hence, length of slant height is 12.5 meters.
