I need help to find the surface area
1 answer:
Answer:
125.6 sq ft.
Step-by-step explanation:
To find the Surface Area of the cylinder, we will need to solve for the area of both bases and the rectangle around the cylinder. We can do this by:
------------------------------
Area of bases: ()
Since we have two bases, we can simply multiply by 2, giving us:
12.56×2= 25.12
-------------------------------
Area of the rectangle: ()
12.56×8= 100.48
Add these two together, giving us:
100.48+25.12= 125.6 sq ft.
