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]

Answer:

128.2

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene, equilateral, isosceles, and right angled triangle.

Two triangles are said to be similar if the ratio of their corresponding sides are in the same proportion.

Since Quadrilateral HIJK is similar to quadrilateral LMNO, therefore the ratio of their corresponding sides is equal to each other. Hence:

[tex]\frac{OL}{HK}=\frac{ON}{KJ}\\\\substituting:\\\\\frac{OL}{42}=\frac{58}{19} \\\\OL=\frac{58*42}{19} \\\\OL=128.2[/tex]

Which histograms are approximately symmetric and bell shaped?

Answers

Answer:

B and E

Step-by-step explanation:

im pretty sure what you have is correct

The correct histograms that are approximately symmetric and bell-shaped are - histograms B, C, and E because they are symmetric and bell-shaped.

A histogram is a convenient form or graphical representation of the frequency distribution of numerical data by means of rectangles. These histograms are found in different shapes and symmetries.

Bell-shaped curve:

if a histogram resembles or looks like a “bell” by joining the interval of rectangles in a curve and has one single peak in the middle of the distribution.In the given histograms only histogram shows a bell-like curve when joining the middle point of rectangles of distribution and also present in symmetry.in the image attach approximate curves are form you can see if it is bell shape and symmetric.

Thus, the correct answer is - Histograms B, C, and E.
