Answer:
<h2>A = 36π yd² ≈ 113.04 yd²</h2><h2>C = 12π yd ≈ 37.68 yd</h2>
Step-by-step explanation:
The formula of an area of a circle:
The formula of a circumference of a circle:
<em>r</em><em> - radius</em>
<em />
We have <em>r = 6yd</em>.
Substitute:
If you want round the answers, then use <em>π ≈ 3.14</em>
B and C (I think they are the same)
The goal of all algebra equations is to isolate the variable. In 3 step you should first make sure both variables are on the same side. To do that make sure you use the inverse.
For example:
6a + 9 = 3a + 15
because 3a is positive you're going to want to subtract it.
6a + 6 = 3a + 15
-3a -3a
_______________
3a + 6 = 15
Now it's a 2 step equation and you solve it on from there.
Answer:
2125
Step-by-step explanation:
CP= x
MP= x+25%= 1.25x
SP= MP-15%= 1.25x*0.85= 1.0625x
SP- CP= 125
- 1.0625x-x= 125
- 0.0625x=125
- x= 125/0.0625
- x= 2000
SP= 2000+125= 2125
------------
Cost price= 2000
Marked price= 2500
Selling price= 2125
