2 2/3= 2 16/24
3 1/4= 3 6/24
4 7/8= 4 21/24
add it all up u get .....
9 43/24=
10 19/24
i think this is right i did it in my head welp

Given:
In the given cone,
Radius of the cone = 7.2 m
Slant height of the cone = 17 m
To find:
The surface area of the cone.
Solution:
The surface area of a cone is:

Where, r is the radius of the cone and l is the slant height of the cone.
Putting
in the above formula, we get




Therefore, the surface area of the given cone is 547.11 square m.
The answer is C. The explanation in the previous comment section is correct
