Answer:
223.07
Step-by-step explanation:
Hey There!
So the first step of this problem is to find the equation for the area of a parallelogram and the area of a circle
The area of a parallelogram is equal to bh
the base is 20 and the height is 15
20x15=300
Now we want to find the equation for area of a circle
to find the area of the circle we use the formula
A = π x radius²
the radius is the diameter divide by 2
14/2=7 so the radius is 7
now we just plug 7 into the area of a circle formula
7²=49
49x3.14=153.86
But because it is a semi circle we divide by 2
153.86/2=76.93
Now to find the area of the object we subtract 76.93 from 300
300-76.93=223.07
Therefore the area of that object is 223.07

Answer:
The value of y for x = 8 is 60 .
Step-by-step explanation:
Given expression as :
For x = 2 , y = 15
Let the equation be written with constant k'
So, y = k x
Or, k =
∴ k =
<u>Now, again </u>
For x = 8
equation can be written as
y = k x
Or, y = × 8
Or, y =
∴ y = 15 × 4
I.e y = 60
Hence The value of y for x = 8 is 60 . Answer
Answer:
C: 12.5
Step-by-step explanation:
The sides x and 11 could be defined as the Adjacent angle and the Hypotenuse. This means that we will use the cos function to solve this.
First we can set up our equation
