Answer:
1803 square meter
Step-by-step explanation:
The surface area of a cone
A=πr(r+V(h2+r2))
where A is the surface area, r is the radius and h is the height
Given that the height of 54 meters and a diameter of 18 meters, the radius is half the diameter hence
radius = 18/2 = 9 m
A = 9π (9 + V(54^2 + 9^2))
= 9π (9 + V2997)
= 9π (9 + 54.74486)
= 1803.068976 Square meters
To the nearest square meter
A = 1803
