<em>Greetings from Brasil...</em>
Here we will apply rule of 3...
This formula, A = πR², its for the whole circle, that is, 360° (2π)
We want the area of only a part, that is, a circular sector whose angle π/6
sector area
2π ----- πR²
π/6 ----- X
2πX = (π/6).πR²
2πX = π²R²/6
X = π²R²/12π
<h3>X = πR²/12</h3>
If Ronisha multiply the area by 1/12 she will get the area of sector with angle of π/6
Answer:
B. The mean is less than the median.
Answer:
is used to prove the given equation.
Step-by-step explanation:
We have given an equation:
We will consider right hand side first
tan x can be written as:
So, on substituting tan x in the left hand side of the given equation we get:
Cancel common term from denominator and numerator which is cosx we get
And we have an identity:
Hence, right hand side is equal to .
Answer: The 4th Venn diagram. (A and B aren't touching, A and B are touching C though.)
9x-22=23+4x
Now you subtract 4x from both sides to get the variable on one side..
5x-22=23
Now solve as you would solve a 2 step equation.
5x=45
Divide both sides by 5 to get the variable by itself.
x=9
