A slightly more accurate value is 38.28 cm^2, when using pi = 3.14
=================================================
Explanation:
The vertical height of the rectangle is 4 cm, which forms the diameter of the semicircle. The diameter cuts in half to 4/2 = 2, which is the radius.
The area of a full circle with radius r = 2 cm is approximately pi*r^2 = 3.14*2^2 = 12.56 square cm.
Cut that in half to get (12.56)/2 = 6.28 square cm. This is the approximate area of the semicircle.
--------
The area of the rectangle is length*width = 6*4 = 24 square cm.
The triangle has its bottom portion of 4 cm (because 10-6 = 4) and its height is 4 cm, so we get the triangle area of base*height/2 = 4*4/2 = 8 square cm.
The last thing we do is add up all the results we got:
6.28 + 24 + 8 = 38.28
That rounds to 38 square cm when rounding to the nearest whole number.

apothem = 15
side = 17.3
Find the area of this regular polygon. (Round to one decimal spot if necessary)
Answers
Answer:
778.5
Step-by-step explanation:
Area of any regular polygon = ( apothem * side length * number of sides ) divided by 2
Given information:
Apothem = 15
Side length = 17.3
Polygon Type = Hexagon ( its important to note that a hexagon has 6 sides )
* Plug in the given values into the formula *
Area = [tex]\frac{15*17.3*6}{2}[/tex]
15 * 17 = 259.5
259.5*6=1557
[tex]\frac{1557}{2} =778.5[/tex]
Hence, area = 778.5 square units

A glass is 2/3 full. Then 40cm^3 of orange juice is poured in. The glass is now 4/5 full What is the total volume of the glass?
Answers
Answer:
The total volume of the glass is 300 cm^3.
Step-by-step explanation:
Let V represent the total glass volume.
Then (4/5)V - (2/3)V = 40 cm^3. The LCD here is 15, so we rewrite this equation as
(12/15)V - (10/15)V = 40 cm^3, or
(2/15)V = 40 cm^3.
Solve for V by multiplying both sides of this equation by (15/2):
(15/2)(2/15)V = (15/2)(40 = 300 cm^3
The total volume of the glass is 300 cm^3.

h: 79 = 23 + 8h
Answers
Answer:
79=23+8h
or,79-23=8h
or,56/8=h
or,7=h
therefore the value of h is 7.
Step-by-step explanation:
Hope it helps you!!
first you have to do the 23+ you have to make 23 into a subtraction problem in these expressions. 79-23= 56
Now you have to cancel out the 8in 8h and do the opposite of multiplication and do division on both sides 8h/8 cancels out and 56 divided by 8 = 7
your answer is 7 hope this helps

The circle is centered at (2,-4) and has a radius of 15.
The circle is centered at (-2,4) and has a diameter of 15.
Answers
The circle is centered at (−2, 4) and has a radius of 15.
i took the test
A circle represented by the equation (x+2)² + (y - 4)²= 225 is centred at (-2,4) and has a radius of 15.
The equation of a circle is represented as follows:
Equation of a circle;(x-h)² + (y-k)² = r²where
(h, k) = centre
r = radius
Therefore, (x+2)² + (y - 4)²= 225 has the following centre and radius.
(x+2)² + (y - 4)²= 15²Then
(h, k) = (-2, 4)
Therefore, the circle is centred at (-2,4) and has a radius of 15

Estimate 91 +94 by first rounding each number to the nearest ten.
Answers
90+90=180
Answer:
about 180
Step-by-step explanation:
(when rounding, numbers 0-4 "stay" meaning you'd round down. If the numbers are 5-9, you round up)
91 rounded to the nearest ten would be 90
94 rounded to the nearest ten would be 90 as well
So, 90 + 90 = 180
Technically though, 91+94 = 185. So rounding this to the nearest ten would be 190.

yes i need help anyone please give me the answer
Answers
Answer:
x = 25
y = 65
Step-by-step explanation:
I'm not sure if I'm right but..
To solve x:
Since there is a 90 degree angle with 65 degrees and x, the total should sum up to 90. (ofc)
90 - 65 = 25 <--- the missing angle (x)
To solve y:
I'm pretty sure that it is also a 90 degree angle because there is a 90 degree across from you, so they should have the same angles. Since you know x=25, You would do this:
90 - 25 = 65 <--- y
