Acaisson has a radius of 2ft and a depth of 5ft . how many cubic feet are in the caisson

Measure the length in feet and the width in feet with the tape measure, then measure the depth in feet with a dip stick if your pond is a square or rectangle.
2
Multiply the length by the width by the depth to get the volume in cubic feet. For example, if your pond is 16 feet long, 8 feet wide and 4 feet deep, multiply 16 by 8 by 4 to get 512 cubic feet.
3
Convert cubic feet to gallons by multiplying the cubic feet by 7.48. In this example, multiply 512 cubic feet by 7.48 to get 3,830 gallons of water in a rectangular pond.

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
