Answer: The area (A) of a circle is a function of its radius (r) and is given by the function A = f(r) = πr2.
Step-by-step explanation: google help
A circular concrete slab is a cylinder. Vol = pi%2Ar%5E2%2Ah
in this cylinder:
r = 18%2F2 = 9 ft
h = 3%2F12 = .25 ft
:
Find the volume in cu/ft:
V = pi%2A9%5E2%2A.25
V = 63.61725 cu/ft
:
Change to cubic yds; (1 cu/yd = 27 cu/ft) and multiply by $40:
Cost = 63.61725%2F27 * 40
Cost = $94.25
In practical terms , they may require you to buy 3 cu/yds , which is $120
Yan na po
So, the ans is A.........
.08 cents per ounce, because 2.40 ÷30 =.08
It is 2/3 I believe
By calculating the difference between the x and y coordinates, and putting it in the rise/run format, you can easily find the slope of the line
