Answer:
D. $3.
Step-by-step explanation:
We have been given that a box of 7 items costs $20.79. We are asked to find the cost of each item.
To find the cost of each item, we will divide total cost by total number of items.


Upon rounding our answer to nearest dollar, we will get:

Therefore, the cost of each item will be approximately $3 and option D is the correct choice.

4^2 + 7^2 = c^2
This is because we know that the hypotenuse (c) is always diagonal to the right triangle, so the legs are 4 and 2 (a and b). There is your equation!

Answer:
C= 2 πr =18.85 m
Step-by-step explanation:
diameter= d= 6m
Radius = diameter/2= 6/2 = 3m
The circumference can be found by two formulas. One by using diameter and the other by using radius.
C= πd = 6* 3.14= 18.85 m
or
C= 2 πr = 2*3.14*3= 18.85 m
Using both the formulas gives the same answer.
The diameter is the line dividing the circle into half passing through the center.
The radius is half of the diameter or the lines which joins the center to the circumference of the circle.
