Height h of cone = 12 cm
Slant height l of cone = 13 cm
We have to find radius of cone.
Let the radius be r.
Radius r of cone = 5 cm
___________________
Total surface area of cone
= 282.6
Therfore,
Total surface area of cone is 282.6 cm²
HOPE IT HELPS YOU..
h=12 cm
pie=3.14
r = ?
l^2=r^2 +h^2
r^2=l^2-h^2
r^2=(13)^2 -(12)^2
r^2=169-144
r^2=25
r=5
T.S.A OF CONE =Pie×r (l+r)
3.14×5 (13+5)
3.14×5×18
=3.14
