How much concrete does it take to fill a hole 25 ft deep and 48 inches diameter hole?

To calculate the volume of concrete needed to fill a hole that is 25 feet deep and 48 inches in diameter, first convert the diameter to feet (48 inches = 4 feet). The radius is then 2 feet. The volume ( V ) of a cylinder is calculated using the formula ( V = \pi r^2 h ). Plugging in the values: ( V = \pi (2^2)(25) \approx 157.08 ) cubic feet. Therefore, it would take approximately 157.08 cubic feet of concrete to fill the hole.
