Answer:
2025.80ft^2

Step-by-step explanation:


Formula: A=2\pi rh+2\pi r^2

Diameter: 25.4ft

Height: 12.7ft

Radius:
(d)/(2)=(25.4ft)/(2)=12.7ft


A=2(3.14)(12.7ft)(12.7ft)+2(3.14)(12.7ft)^2\\A=1012.90ft^2+1012.90ft^2\\A=2025.80ft^2

Answer:

A≈2026.8

Step-by-step explanation:

By using the formula,

A=2πd/ 2h+2π(d /2)^2

we can find the surface area of the cylinder.

(PS. dont mess up your order of operations!)

Hope it helps!
