Ok so the radius is half the diameter, and the diameter is half the circle. And the area is the space inside a circle. And pie is 3.14.
So if your radius is 10 then you will multiply 10 x 10 to get 100. Then multiply 100 x pie or 3.14 which you will get, 314cm². So your answer is 314cm²
The formula for an area of a circle is radius x radius = ?
Then multiply pie, 3.14 by your new radius x radius, and you got your answer.
Answer:
They both represent the same equation
Step-by-step explanation:
Given
The question is not properly presented.
However, I can pick the following from the question.
Paul's workings:
Where
and
So:
Seth's workings:
Required
Determine if both workings represent the same equation
Step 1: Analyze Paul's workings
Paul applied slope intercept to determine the equation of the line and his workings is correct.
Step 2: Analyze Seth's workings
Seth applied slope formula in determining the equation of the line and up till where Seth's stopped, Seth was correct.
The next step is to complete Seth's workings as follows:
Seth's workings:
Open bracket
Collect Like Terms
Reorder
Comparing the end results of Seth and Paul's workings.
We have that both results are the same.
i.e.
<em>Hence, they both represent the same equation</em>
Answer:
x = 3
Step-by-step explanation:
Once again we want to use the relationship stated earlier
Where A * B = C * D
Once again imagine that the segments in the given problem have letters
A = x
B = 12
C = x + 1
D = 9
Now we create an equation using the relationship
12 * x = 9(x+1)
now we solve using basic algebra
step 1 distribute the 9 to the x and the 1
9 * x = 9x
9 * 1 = 9
now we have 12x = 9x + 9
step 2 subtract 9x from each side
12x - 9x = 3x
9x - 9x cancels out
now we have 3x = 9
step 3 divide each side by 3
3x/3=x
9/3=3
we're left with x = 3
$149. If you take 745, times it by .20 you get 149, this is similar to figuring out how much an item is on sale.
