Question

Find the total surface area of a cone, if its radius 14 m and slant height 49 m. (Use π=227).
  1. 2762 m2
  2. 2772 m2
  3. 2672 m2
  4. 1772 m2

A
2772 m2
B
2672 m2
C
1772 m2
D
2762 m2
Solution
Verified by Toppr

Given r=14m,s=49m

Then, Surface area of a cone
= πrs+πr2

=227×14×49+227×14×14

=2156+616

=2772m2.

Therefore, option B is correct.
