Answer:
5
Step-by-step explanation:
If you multiply the square root of any number by the square root of the same number you get that number.
To answer your question, it is shown in the graph below.
y=-3x-6 is parallel to y=-3x-2
We need the radius to find the surface area. Since we have the circumference we can use that to find the radius.
C = 2πr
23 = 2(3.14)r
23 = 6.28r
23/6.28 = r
3.66 = r
Now use the radius to find the surface area.
SA = 4πr²
SA = 4(3.14)(3.66)²
SA = 168.33
Surface area is C. 168 cm²

They sold 17 bags because you have to divide the total(127.50) by the price(7.50). So the equation is 127.50/7.50=17
Given:
Radius of small circle = 4 in.
Width of gray border = 2 in.
To find:
The area of the gray border.
Solution:
We have, radius of small circle:

The width of gray border is 2 in. So,t he radius of the larger circle is:


Now, area of gray border is the difference for area of larger circle and smaller circle.


Substituting
in the above formula, we get




The area of the gray border is
square inches. Therefore, the correct option is D.
