Step-by-step explanation:
I got 5 inches b/c 8-5 1/4 equals to 2 3/4. 2 3/4 is equal to two feet and 9 inches. 28 inches is equal to two feet and four inches. Nine inches minus four inches equals five inches.
The area of the given diagram is 29.817 square centimeters. The given diagram is combination of rectangle and semi circle.
Step-by-step explanation:
The given is,
Given diagram is combination of Rectangle and Semi circle.
Step:1
Res the attachment,
Area of given diagram = Area of A + Area of B..............(1)
Step:2
For A,
The A section in the given diagram is semi circle,
Diameter of semi circle = Total distance - ( 2+3)
( ∵ 2, 3 are top distance in the given diagram)
![= 10 - 5](https://tex.z-dn.net/?f=%3D%2010%20-%205)
Diameter, d = 5 cm
Radius, ![r = \frac{d}{2}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7Bd%7D%7B2%7D)
![r = \frac{5}{2}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B5%7D%7B2%7D)
r = 2.5 cm
Area,
........................(2)
![= \frac{19.63}{2}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B19.63%7D%7B2%7D)
![A_{A} = 9.8174 cm^{2}](https://tex.z-dn.net/?f=A_%7BA%7D%20%3D%209.8174%20cm%5E%7B2%7D)
Step:3
For B,
Area of rectangle is,
.....................(3)
Where, l - Length = 10 cm
b - Width = 2 cm
Equation (3) become,
![= (10)(2)](https://tex.z-dn.net/?f=%3D%20%2810%29%282%29)
![= 20](https://tex.z-dn.net/?f=%3D%2020)
Area of B,
= 20 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
Step:4
From the equation (1),
Area of given diagram = 20+ 9.81747
Area = 29.817 square centimeters
Result:
The area of the given diagram is 29.817 square centimeters. The given diagram is combination of rectangle and semi circle.
Answer:
18
Step-by-step explanation:
60 total fourth graders and 43 are girls. To find the number of boys, subtract.
60 - 43 = 17 boys
If 5 girls were absent, subtract.
43 - 5 = 38 girls present
If 4 boys were absent, subtract.
17 - 4 = 13 boys present
Therefore, there were 13 boys present.
Best of Luck!
