Root (1,0)
Domain x ∈ [-1,1]
Virtical intercept (0, π/2)
x/sqrt 1+x^2
This is an irrational number because it cannot be written as a fraction
Answer:
12.56 square units
Step-by-step explanation:
The formula for circumference is
C = 2πr
Our circumference is 12.56. Using 3.14 for π, we have
12.56 = 2(3.14)r
12.56 = 6.28r
Divide both sides by 6.28:
12.56/6.28 = 6.28r/6.28
2 = r
The area of a circle is given by the formula
A = πr²
Using 3.14 for π and our radius of 2, we have
A = 3.14(2²) = 3.14(4) = 12.56.
the answer should be (3,2) since it's in the shaded region
