What is the approximate area of the figure? Help pls.....
Vaselesa [24]
Okay, first we need to calculate the area of the rectangle. 

Area of Rectangle- 16 x 6 = 96 

Next, we need to calculate the area of the semicircles. 

Formula: Radius x Radius x pi (3.14) = Area of circle

 Since we know that the diameter is 6 we can figure out the radius. 
The radius is half of the diameter. So our radius is 3. 

3 x 3 x 3.14 = 28.26

Since it's a semi circle we now need to divide by 2. 

28.26 divided by 2 = 14.13 

Then, we add.  

Area of rectangle 
+
Area of 2 semi circles 

96 + 14.13 + 14.13 = Total Area of The Figure 

So our answer is 124.26

Which graph could represent y, the amount owed on a car loan, as regular payments are made each month, x?
k0ka [10]

Answer:

Graph # 4

Step-by-step explanation:

If regular payments are paid each month, there would be no change in the slope of the line and the slope will be 0.

Amount owed = y

Number of car payments paid = x

So, if there is no change in y, the line will be a straight line parallel to x-axis.

\rule[225]{225}{2}

Hope this helped!
