Answer:
2813 sq.m.
Step-by-step explanation:
Height of cone = 48 m
Diameter of cone = 28 m
Radius of cone = [tex]\frac{Diameter}{2} = \frac{28}{2}=14 m[/tex]
Slant height l = 50 m
Total Surface area of cone = [tex]\pi r l +\pi r^{2}[/tex]
= [tex]3.14 \times 14 \times 50 +3.14 \times 14^{2}[/tex]
= [tex]2198 +615.44[/tex]
= [tex]2813.44 m^2[/tex]
Thus the surface area of the cone to the nearest whole number is 2813 sq.m.
Hence Option C is correct.
