Answer:
Given the area of the base of a cone is 616 cm
2
.
If r be the radius of the base of the cone then
πr
2
=616
or,
7
22
×r
2
=616
or, r=14.
Also, given height (h)=48 cm.
Then slant height (l)=
48
2
+14
2
=2
625
=50 cm.
∴ total surface area of the cone =πr(r+l)=
7

×14×64=2816 cm

Answer:
2200 sq.cm
Step-by-step explanation:
Area of the circular base= 616 sq.cm
By simplification we get radius = 14 cm.
By further simplification we get l= 50 cm.
CSA of the cone= pie X l x r
=22/7 X 14 X 50
= 2200 sq.cm
Hope this answer helps. Plz mark me as the brainliest.
