I need help. So it says to find the shaded area, and I'm not really good a things like this
Answers
Answer:
86 cm²
Step-by-step explanation:
1) Calculate the area of the square
[tex]A=lw\\A=20*20\\A=400[/tex]
Therefore, the area of the square is 400 cm².
2) Calculate the area of the circle
[tex]A=\pi r^2\\[/tex]
[tex]\pi[/tex] we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.
[tex]A=3.14*10^2\\A=3.14*100\\A=314[/tex]
Therefore, the area of the circle is 314 cm².
3) Subtract the area of the circle from the area of the square
[tex]A=400-314\\A=86[/tex]
Therefore, the area of the shaded region is 86 cm².
I hope this helps!
Step-by-step explanation:
Given,
One side of the square = 20 cm
Therefore, Area of the square = side × side
= 20 cm × 20 cm
[tex] \: \: \: \: \: \: \: \: = 400 {cm}^{2} [/tex]
Also, known that
One side of the square = Diameter of the circle = 20 cm
So, radius of the circle = 20/2 cm = 10 cm
Therefore, area of the square
[tex] \: \: \: \: \: \ \: \: \: \: = \pi{r}^{2} [/tex]
[tex] = 3.14 \times {(10cm)}^{2} [/tex]
[tex] = 3.14 \times 100 {cm}^{2} [/tex]
[tex] = 314 {cm}^{2} [/tex]
Hence, area of the shaded region is
= Area of the square. - Area of the circle
[tex] = 400 {cm}^{2} - 314 {cm}^{2} [/tex]
[tex] = 86 {cm}^{2} (ans)[/tex]

Step-by-step explanation:
Latrell wants to fill his water bottle between classes, but the water fountain next to his classroom is frustratingly slow. It takes Latrell 5 seconds to get each ounce of water in his bottle. There is a proportional relationship between the amount of water (in ounces) Latrell puts in his water bottle, x, and how long in seconds) it takes to get that amount, y. Graph this relationship. Select two points to draw a line.
what is the slope of the line? _____
Answers
Answer:
Step-by-step explanation:
Slope = rise/ run, or y∨2 - y∨1/ x∨2 - x∨1
5-10/ 1-2 =
-5/-1 = 5
The slope of the line drawn from the given data is 5.
What is the slope?A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).
Given this, Latrell fills his bottle with one ounce of water in five seconds. The amount of water Latrell puts in his water bottle (in ounces), x, and the time (in seconds) it takes to get that amount, y, are proportionate. This connection can be graphed. Since, the line will pass from the origin(0, 0).
Since given y is the directly proportional equation of the line will be;
y = mx
where m is the slope of the line
Also given, filling the bottle at every ounce requires 5 seconds of time. hence, the line will go from (1, 5)
Thus, the value of the m will be;
5 = m *1
m =5
Therefore, the slope of the line is 5.

52.38 inch² & 261.90 inch²
Step-by-step explanation:Here we need to find the area of the sector . So according to formula we know the area of sector as ,
[tex]\boxed {\sf Area_{(sector)}= \dfrac{\theta}{360}\times \pi r^2 }[/tex]
Here we can see that the central angle subtended by the arc is 60° and the radius of the circle is 10 inches . So the required area would be ,
=> Area = ∅/ 360° × π r²
=> Area = 60°/360° × 22/7 × (10in.)²
=> Area = 1/6 * 22/7 * 100 in²
=> Area = 52 .380 in²
★ Hence the area of the red sector is 52.38 inch²._________________________________
Now let's find out the area of blue sector .The angle subtended by the arc will be (360-60)°=300° .
=> Area = 300/360 × 22/7 × 100 in²
=> Area = 261. 90 in²
★ Hence the area of blue sector is 261.90 inch².[tex]\boxed{\red{\sf Area _{(red \ sector )} = 52.38 in^2 }}[/tex]
[tex]\boxed{\blue{\sf Area _{(blue \ sector )} = 261.90 in^2 }}[/tex]
