Pls can someone help me with math pls I’m this is my last points..

Answer:

Please read all of this! Underlined things are the answers. The area of the entire circle is 19.625

Step-by-step explanation:

(This is a circle so the middle line is the diameter. According to the attachment, the diameter is 5 cm. To find the area, we have to multiply π and the radius squared. The radius is half of the diameter.

5 ÷ 2 = 2.5

2.5² = 6.25

π = 3.14

3.14 x 6.25 = 19.625)

Ignore the top I just realized what I'm supposed to do but I left it there just in case you need help!

<u>The right and left shaded regions areas are 6.28 each.</u>

4 ÷ 2 = 2

2² = 4

3.14 x 4 = 12.56

Since this is a semi circle, we cut it in half.

12.56 ÷ 2 = 6.28

To find the top and bottom shaded region's areas, repeat the same steps.

3 ÷ 2 = 1.5

1.5² = 2.25

3.14 x 2.25 = 7.065

7.065 ÷ 2 = 3.5325

<u>The areas of the the top and bottom shaded regions are 3.5325 each.</u>

PLS HELP ILL GIVE BRAINLIEST<br> What are the coordinates of the center of the ellipse?
yulyashka [42]

Answer:

Step-by-step explanation:

Standard equation of an ellipse,

\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1

(h, k) is the center of the ellipse

Value of a = Distance of the center from the vertex

b = Distance of the center from the covertex

From the picture attached,

a = Distance of the center (h, k) from the vertex (2, -2) = 3 units

b = Distance of the center (h, k) from the co-vertex (-1, 0) = 1 unit

Center of the ellipse (h, k) = (-1, -2)
