The total surface of the base is 2206 square feet (approx). The area of the top, if there is any, will be the same.
The area of the side walls is 1582 square feet (approx).
the sq. footage of the circle would be 3.14(radius squared). if the diameter is 200ft, then the radius is 100ft. So, 3.14(100x100)= 3.14(10,000)= 31,400 sq. feet
Simply put multiply 15 by 40 to get the square footage. This would be 600 square feet.
Area = pi*r2 = pi*4.52 = 63.62 sq feet (to 2 dp)
The square footage would be 25 times 12 or 300 square feet.
10,000 square feet.
Surface area for a circle is pi * radius squared If the diameter is 25 feet, then the radius is 12.5 feet, and the square footage is pi * 12.5 * 12.5 Or about 491 square feet

Approx 755 square feet.
379.94 square feet
132.7 square feet.
8 square feet
Its total surface area is 15614 square feet.
2.25pi feet squared or 7.068583471 sq. feet

There are two ways to answer your question. If you mean the circle is 16 feet wide (diameter), then the square footage is 201.06 square feet. However, if you mean the circle is 16 feet around (circumference), the square footage will be 20.372 square feet.
Area of a circle in square feet = pi*radius2
Multiply the diameter of the cylinder in feet by pi. (3.141592652), then multiply that answer by the length of the cylinder in feet.
