Lets split this into two parts; a semi circle and triangle. We can solve fro the area of both individually first.
Area of the Semi Circle:
Formula: A = (πr²)/2
The radius is the diameter divided by two (16 / 2 = 8)
A = (π*8²)/2
A = (π64)/2
A = 200.96/2
A = 100.48 meters
The area of the semi circle is 100.48 meters
Area of the Triangle:
Formula: A = bh/2
A = 16*12/2
A = 192/2
A = 96 meters
The area of the triangle is 96 meters.
To find the total area of the shape, we can add.
100.48 + 96 = 196.48 meters.
Best of Luck!
Okay I'm not too sure on this but I believe it is the third one.
I hope this helps!!
Answer:
calculate the rise over the run.
therefore, it's -8/7

B and C.
When multiplying binomials, you use a form of the distributive property. With how your lesson has it here, it formed a multiplication table instead.
If you were to complete the table with the actual values, you'd find that:
A=-8x^2
B= 12x
C= -2x
D= 3
As you can see, B and C are the only like terms, or in other words, they can be added together since they have similar variables
21. Find the unit rate ($ per fl oz). Compare the two prices.
22. Multiply 2 3/5 by 7, and 5 3/4 by 4. Add those together and get the answer.
Hope that helps!
