The correct option is A 2816 cm2
Here, we need to calculate the total surface area of the cone.
T.S.A. of the cone = π r(1+r)
=πrl+πr2
where πr2 is the area of the base of the cone.
Given: πr2=616 cm2
⇒227×r2=616
⇒r2=616×722
⇒ r = 14 cm
Also, h = 48 cm
Now, l=√h2+r2
=√482+142
=√2304+196
=√2500=50 cm
So, T. S. A of conical tent =πrl+πr2
=227×14×50+616
=2816 cm2
