HEY......
To find the CSA we need radius and skant height.
raduis can be finded by GIVEN AREA OF BASE.
AND
slant height can be finded by L^2= R^2+ H^2.

Step-by-step explanation:
Area = 3850
h = 84 cm
pie r2 = 3850
22/7 × r2 = 3850
r2 = 3850 × 7 /22
r = 35
c.s a of cone = pierl
l = root h2 + r2
l = root 1225 + 7056
l = root 8281
so l = 91
22 /7 ×35×91 = 10010
