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>
(2x+1) + (2x+3) + (2x+5) + (2x+7) + (2x+9) = 145
10x + 25 = 145
10x = 120
x = 12
2x + 1 = 25
Sequence = 25 +27 +29 +31 +33
Third number = 29
Answer:
-36+7x
Step-by-step explanation:
A: ∠3 and ∠2
E: Since ∠3 and ∠2 lie on the same line and on a straight line, they must be supplementary as they must add up to 180° to satisfy the condition of a straight line.
