Question

If the area of the base of a right circular cone is 3850 sq cm and its height is 84 cm , then the curved surface area of the cone is

Answer 1

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.

Answer 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
