What is the area of the blue shaded figure if A=28 cm and B=14 cm?
Use 3.14 to approximate π.
Answer:
153.86[tex]cm^{2}[/tex]
Step-by-step explanation:
For the white semicircles:
B=14cm is also the diameter, we know r=1/2diameter, so r=1/2(14)=7
Awhite=1/2π[tex]r^{2}[/tex]
Awhite=1/2π([tex]7^{2}[/tex])
Awhite=76.93[tex]cm^{2}[/tex]
For the blue semicircle:
B=14cm is also the radius
Ablue=1/2π[tex]r^{2}[/tex]
Ablue=1/2π([tex]14^{2}[/tex])
Ablue=307.72[tex]cm^{2}[/tex]
Shaded area:
Ashaded=Ablue-2(Awhite)
We use this equation since there are two white semicircles.
Ashaded=307.72-2(76.93)
Ashaded=153.86[tex]cm^{2}[/tex]
Answer:
615.44cm^2
Step-by-step explanation:
the big semicircle has a radius of 28cm
then you find the area of the big semicircle which is 1/2 x 28^2 x pi
pi=3.14
28^2=784
1/2 x 784 x 3.14=1230.88
the small semicircle has a radius of 14cm
1/2 x 14^2 x pi
1/2 x 196 x 3.14=307.72
since there are two small semicircle you need to times 307.72 by 2
307.72 x 2=615.44
now to find the area of the blue shaded you need to do
1230.88-615.44=615.44cm^2
In each equation, select an operation to make the equation true.
Choices are +, -, x, and / (divide)

Mariko has an 1:80 scale-drawing of the floor plan of her house. On the floor plan, the dimensions of her rectangular living room are
1 7/8 inches by 2 1/2 inches.
What is the area of her real living room in square inches? Show work to explain how you found your answer.
Answer:1 inch is actually 80 inch so:
1 7/8 x 80 is true length of side 1 and
2 1/2 x 80 is true length of side 2 of room
Step-by-step explanation:
the area is side 1 x side 2 in sq inches
then change square inches to square feet for your final answer
Answer:
14000
Step-by-step explanation:
multiply by 80, and then multiply the height and width together to get your answer!
Please Explain How to Solve.
Can somebody explain how to find an area of a square?
Please note that the area's side lengths are all the same.
(The side lengths are all 1/3 or also known as 0.3333)
Answer:
0.66653334
Step-by-step explanation:
The area of the face of the square is the side length x the side length. So 0.3333 x 0.3333 = 0.11108889. Since a square has 6 sides, multiply 0.11108889 with 6. So it equals 0.66653334.

Answer:
There are six faces on the solid.
There are twelve edges on the solid.
There are eight vertices on the solid.
Step-by-step explanation:
The 3-D solid shape is a cube.
A cube is a regular hexahedron.
Hexahedron is a polyhedron with six faces (regular meaning all six are square).
So, there are six faces on a cube.
A cube has 12 edges because all faces are squares and congruent to each other, all 12 edges are the same length.
A vertex is a corner where edges meet. The plural is vertices.
a cube has eight vertices, a cone has one vertex and a sphere has none.

A fruit seller packed some apples into 15 small cartons and 20 big cartons. Each big carton contained 15 more apples than each small carton. 1/4 of the total number of apples were packed in small cartons. How many apples did the fruit seller pack altogether?
Answer:
720 apples
Step-by-step explanation:
Let A be the number of apples in the small pack.
QTY for Small Cartons is 15A,
QTY for Big Cartons is 20(A+15) = 20A+300
From small cartons makes 25% or 1/4 of total, means the big carton makes 75% of total, or 3/4 of total. This also means the qty in big carton is 3 times of small carton
20A+300 = 3X (15A)= 45A
300 = 25A
A=12
Altogether = 15A+(20A+300) = 720 Apples

b² - 5c if b = 15 and c = 9
Answer:
180
Step-by-step explanation:
Here,
b=15
c=9
Now,
[tex]=b^{2}-5c\\\\=15^{2} -5*9\\\\=225-45\\\\=180[/tex]
Answer:
180
Step-by-step explanation:
b^2-5c
Substitute 15 in for b
15^2=225 -> 225-5c
Substitute 9 in for c
5(9)=45
225-45 = 180

Step-by-step explanation:
Translate these into numerical values: 3 3/9 + 7 6/11 = 10 87/99
Find a common denominator or multiple that your denominator's (9 and 11) share. Their lowest common multiple is 99.
Take 3 3/9's and multiple the denominator by 11 to get your denominator of 99. What you do to your denominator also must be reflected in your numerator, so multiply it by the same factor of 11. You will get 3 33/99
Repeat for 7 6/11. Multiply your denominator (11) by 9 to get your denominator of 99. Do the same in the numerator (6) to get 54.
Now add your new values. 3 33/9 + 7 54/99
Your fractional values will add up to 87/99, and your whole number values will add up to 10. In this case, your fractional values do not exceed 1, so there is no need to work any further. Your final answer is 10 87/99
