I assume you mean a diameter of 3 feet. Divide the diameter by 2, to get the radius. Then use the standard equation for the area of a circle:

area = π x radius^2 = π x (3 ft ÷ 2)^2 = 9/4 π sq ft ≈ 7.07 sq ft

What is the area of 8ft 3ft 3ft round to the nearest whole number?

It depends on the shape. A 8ft-3ft-3ft triangle is impossible, a circle needs only one measure, a square only 1, a rectangle 2. Other quadrilaterals need more than 3. So the shape is indeterminate and, therefore, it is impossible to calculate the area.


What is the total area of a rectangle with a length of 4 ft width of 3ft and height of 6 ft?

Why does a 16 foot fence arranged 1 ft by 7ft make a smaller area than when arranged 3ft by 5ft?

Because Area and Perimeter are not directly linked. If you were to make the fence into a triangle you would get another area, a circle would give a fourth.
