Assuming a circular pool, divide the diameter by 2 to get the radius, then use the formula for the area of a circle. The depth is not relevant for this problem.

132.7 square feet.
The area of a hole 4 feet in diameter and 19 feet deep is: 76 square feet. (4 x 19 = 76).
Area of a circle in square feet = pi*radius2
Area of the circle: pi*8^2 = 201 square feet rounded

132.7 square feet.
379.94 square feet
Approx 755 square feet.
Its total surface area is 15614 square feet.

The area of a hole 4 feet in diameter and 19 feet deep is: 76 square feet. (4 x 19 = 76).
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.
It is 62 times 24 = 1488 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
Area of a circle in square feet = pi*radius2
