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:
The number of candles each girl needs to sell so that the total amount raised is the same for both is
<em>Hailey </em>70 candles
<em>Kacie </em>40 candles
Step-by-step explanation:
Let
x------> the number of candles sold
y----> total amount raised
we know that
<em>Hailey's equation</em>
-----> equation A
Please note that Hailey has already raised $160, so he has sold 40 candles.
<em>Kacie's equation</em>
-----> equation B
Please note that Kacie has already raised $70, so he has sold 10 candles.
equate equation A and equation B solve for x
The number of candles each girl needs to sell so that the total amount raised is the same for both is
<em>Hailey</em>
40+30=70 candles
<em>Kacie</em>
10+30=40 candles
