Answer:
Step-by-step explanation:
Ok so the formula for a circle is
A=πr2
The diameter of the semicircle is 15, so if you divide that by 2 you will get a radius of 7.5. Then, the next part of the formula is to square the radius, and to do that you need to multiply the radius by itself. You will then get an answer of 56.25. And then finally, you multiply 56.25 by pi, which is 3.14 and get 176.625. Then for the quarter circle, you have 2 side lengths of 15 feet. To find the area of the quarter circle, do pi times the radius(15), and square the answer. Then, divide the answer by 4 to get the quotient, 554.6025. 176.25 + 554.6025 is 730.8525
. That rounded to the nearest 100th is 730.85.
I really hope this helped and I'm sorry if it is incorrect.
Answer:16y I think
Step-by-step explanation:
Take out the y, 2+5-3 is 4, and to the second power is multiplying 4 twice, so 16. theyre all have the same variable to the right, so 16y
Answer:
Option D. a^2+6ab-2ba
Step-by-step explanation:
Option D because we have like terms: 6ab and -2ba=-2ab, then
a^2+6ab-2ba=a^2+6ab-2ab
Simplifying on the right side of the equation adding like terms:
a^2+6ab-2ba=a^2+4ab
If you see the slope intercept form that’s the y coordinate
