Answer:
A) 50
Attached is the image of the figure.
Step-by-step explanation:
Area of a circle can be expressed as;
Area A = πr^2 ......1
Where;
r = radius
From the attached image, the shape is a Circle and the diameter of the circle is 8 units.
Diameter d = 8
Radius r = diameter/2 = 8/2 = 4 units
Substituting the radius into equation 1;
Area A = π × 4^2 = 16π
Area A = 50.265
Area A = 50 square units (approximately)
It’s been awhile since I’ve done a problem like this but I believe it’s solved as below:
The area of a circle is equal to πr2. That will tell you the entire area of the circle. Then you would need to divide that by 2 to get the area of the 180° arc.
So, the area of this circle is 153.94 square meters. If you divide that by 2 (since 180° is half of a circle) you would get 76.97 square meters.
Answer:3.6 m
Given:10cm=2m
Then, 5cm=1m
Therefore, (18/5)= lenght I'm meters on blueprint scale
(18/5)=3.6m
Answer:
Let be the amount of parts the student answered correctly. Suppose that is a function between and the score of a student's project. As the student initially receives a fixed points for turning the project in and points for each correct part, the function is initially:
When the students receive points for each correct part, the coefficient of changes, as the amount of points received per correct answer increases. Thus:
.
