Gregory wants to fence three sides of a rectangular exercise yard for his dog. The fourth side of the exercise yard will be a side of the house. He has 120 feet of fencing available. Find the dimensions that will enclose the maximum area.

The three sides that aren't the house would use 40 feet each for the maximum area.

Step-by-step explanation:

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
