Yes, that seems like the right answer. So no they dont have enough paint to finish the job on Wednesday.
Answer:
b=c+1/2a
Step-by-step explanation:
hope this helps :)
You need to first make everything positive:
x^2=36
Then you need to get the square root of each side:
x=6 or -6

Answer:
Step-by-step explanation:
Given
--- The radius of each
Required
The area between them
See attachment for illustration of the question. (figure 1)
First, calculate the height of the equilateral triangle formed by the 3 radii (See figure 2)
Using Pythagoras theorem, we have:
Collect like terms
Take square roots
Expand
Split
Now, the area of the equilateral triangle can be calculated using:
Where
Next, is to calculate the area of the sector formed by 2 radii in each circle (figure 3).
Since the radii formed an equilateral triangle, then the central angle will be 60. So:
For the three circles, the area is:
Subtract the areas of the sectors (A2) from the area of the equilateral triangle (A1), to get the area between them.
Approximate
