Sandra has designed this open container. The height of the container is 35 cm.
(a) The cross section of the container is given below. Find the area of the following figure.
Answers
Answer:
329.87cm2
Step-by-step explanation:
Actually include the question next time.
Full Bottom Is semi circle.. find the area of the semicircle that's A1...
Then find the area of the smaller circle marked in red.. that's A2...
Then A1 - A2 will give you bottom area...
Now move to top one... Top one is a semi circle.. find its area A3...
So add both A3 with A1-A2...
Total will give the area of the shape
The area of the cross-section of the container will be 329.87 cm²
To determine the area of the cross-section of the open container, we need to find the area of the semicircle and add them up.
Area of the container:
Area = (2π r²) + (2πrh)
We are Given, the diameter are 17.5 cm and 6.5 cm respectively.
Diameter of the complete circle will be;
(17.5 + 6.5) =24.0
Area of complete circle is π x( 12)²
452.16 cm²
Therefore, the area of the circle A is (π x( 17.5/2)²
= 240.40 cm² (approx).
Therefore, the area of the circle B is (π x( 6.5/2)²
= 33.166
Total area of circle = 452.16 cm² - 33.166
Area = (452.16 cm² - 33.166 cm² ) + (2x 3.14 x 12 x 35)
Area = 329.87 cm²

I am stuck on a geometry lesson. It is on the Angle Sum Theorem. It said we have an obtuse trisngle with angles 1, 2, and 3. Then they extend the line out as a dashed line top and bottom parallel to each other. It then he says we have angle 1 value would also be true on the opposite side of the triangle like as a transeversal intersected 2 parallel lines making those angles alternate interior angles. He does the sme with 2. then says 1 plus 2 plus 3 equal 180 and says it twice. What does that mean?

Write an equation in slope intercept form for the line that has a slope of 1/4 and passes through the point (0, -2)
Answers
Step-by-step explanation:
the general slope intercept formula is
y = ax + b
a is the slope of the line.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the equation and solve for b :
-2 = (1/4)×0 + b
b = -2 (as expected)
the full line equation is
y = (1/4)x - 2

Answer:
F=(9C+160)/5
Step-by-step explanation:
C=5(F-32)/9
Simplify to 5F-160/9=c
multiply by 9 on both sides : 5F-160=9C
add 160 to both sides: 5F=9C+160
Divide by 5 on both sides: F=(9C+160)/5
Simplify: F=9/5c+32
Answer:
[tex]F=\frac{9C}{5}+32[/tex]
Step-by-step explanation:
The subject of the formula is the variable that's being worked out. Originally this was C. They want us to make F the subject of the formula.
[tex]c=\frac{5(F-32)}{9}[/tex]
To do this we first need to distribute 5.
[tex]C=\frac{5F-160}{9}[/tex]
Divide 5F-160 by 9.
[tex]C=\frac{5}{9}f-\frac{160}{9}[/tex]
We can then swap sides to make it easier.
[tex]\frac{5}{9}f-\frac{160}{9}=C[/tex]
We then add [tex]\frac{160}{9}[/tex] to each side.
[tex]\frac{5}{9}f=c+\frac{160}{9}[/tex]
We can then find F by multiplying by 9/5 or dividing by 5/9.
[tex]F=\frac{9}{5}(C+160/9)[/tex]
We then can simplify by multiplying.
[tex]F=\frac{9C}{5}+32[/tex]
