Imagine cutting this shape into two semi-circles and one rectangle.
------------------------------------------------------------------------------------------------------
Each semi-circle has a diameter of 36 metersThe radius would be (36/2) = 18 meters.--------------------------------------------------------------------
We know the area of a whole circle which is π[tex]r^{2}[/tex]
The formula of area of a semi-circle: 1/2(π[tex]r^{2}[/tex])because a semi-circle is basically half of the whole circle!
However, since we have two equal semi-circles...we can just put them together and solve for the whole circle's area.
for reference:
1/2(π[tex]r^{2}[/tex]) + 1/2(π[tex]r^{2}[/tex]) = 2/2(π[tex]r^{2}[/tex]) = π[tex]r^{2}[/tex]
----------------------------------------------------------
First, the area of rectangle: length times width = 84 x 36 = 3024 square meters
Anyways, since we have to sub in 3.14 for π
Area of a whole circle: (3.14 x [tex]r^{2}[/tex]) = (3.14 x [tex]18^{2}[/tex]) = 1017.36 square meters
-----------------------------------------------------------
3024 + 1017.36 = 4041.36 square meters

Joy recorded the distances she walked each day for six days. How far did she walk in 6 days? Enter your answer as a mixed number in simplest form.
Answers
Answer:
[tex]2\frac{1}{6}[/tex]
Step-by-step explanation:
The question is not complete, but I would show how to solve a similar question.
Joy recorded the distances she walked each day for five days. How far did she walk in 5 days?
Solution:
We can see that Joy distance is recorded in the dot plot. From the dot plot, we can see that she walked 1/3 miles each day for three days, 1/2 miles for one day and 2/3 miles for one day. Therefore, to get the total distance walked, we just have to sum the individual distance that she walked each day. Hence the total distance is given as:
[tex]Total \ distance=\frac{1}{3} +\frac{1}{3} +\frac{1}{3}+ \frac{1}{2}+ \frac{2}{3} =\frac{13}{6}=2\frac{1}{6}[/tex]

Help I don’t get it..
Answers
Answer:
Step-by-step explanation:
the shape looks like a cube.. and maybe they say something about that outside of the picture, even but assuming that it is a cube, we know all the sides are the same.
we also know that the area of one side of the cube is 3 [tex]\frac{1}{4}[/tex]
so multiply that
W x L = area
3 [tex]\frac{1}{4}[/tex] * 3 [tex]\frac{1}{4}[/tex] = area
10 [tex]\frac{9}{16}[/tex] = area
10.5625 = area
those two answer above are the same .. just one is in fractions and one is in decimals
there are 6 sides on a cube, so multiply the above answer by 6
6* answer = 63.375
63 [tex]\frac{3}{8}[/tex] ( this is your answer)
both of those are also identical , but look different for the reasons I mentioned above
use which ever from seems better to you. :)

Answers
Answer:
sinθ = [tex]\frac{24}{25}[/tex]
Step-by-step explanation:
By applying Pythagoras theorem in the given triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
= (24)² + 7²
Hypotenuse = √625 = 25
By applying sine rule in the given triangle,
sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
Since, measure of opposite side = 24
Measure of hypotenuse = 25
Therefore, sinθ = [tex]\frac{24}{25}[/tex] will be the answer.

Which value of x results in equal outputs for
j(x) = 3x − 2
and b(x) = |x + 2|
Answers
Answer:
Step-by-step explanation:
J(x)=b(x)
3x-2=|x+2|
3x-2=±(x+2)
when 3x-2=x+2
3x-x=2+2
2x=4
x=4/2=2
when 3x-2=-(x+2)
3x-2=-x-2
4x=-2+2=0
x=0
it is rejected as 0-2≠|0+2|

The bearing of B from C is 22° counterclockwise
Step-by-step explanation:
∠CAB = 210 - 90 = 120°
Extend a line from A to the west.
drop a perpendicular line from that line to point C.
Let's call the point at the perpendicular point, M.
∠MAC = 180° - 120° = 60° because they are supplementary.
Now we have a right ∠CMA with a known hypotenuse and a known angle.
Solve for MA:
cos 60° = MA/3.8 = 1.9
Solve for MC:
sin 60° = MC/3.8 = 3.29
MB = 1.9 + 6.4 = 8.3
tan ABC = 3.29/8.3 = 21.62°
