Answer:
$15700
Step-by-step explanation:
To find the cost, you multiply $50 by the area of the floor. The floor must be a circle ("radius"), so to find the area of a circle, use the formula
Multiply 314 sq. ft. by the cost per sq. ft.
314 x 50 = 15700
The answer is 21 because yeah
The last one. If it rose 539 ft then that'd be 539 and 539 - 539 = 0
Using y1-y2 divided by x1-x2, 25-3=22 and 10-1=9 22/9 can be written as a mixed number (2 4/9) kept the same or written as a decimal, (2.4).
