Answer:
A=346.46
Step-by-step explanation:
Using the formulas
A=πr2
d=2r
Solving forA
A=1
4πd2=1
4·π·212≈346.36059
Answer:
5
Step-by-step explanation:
The easiest way to do this problem is to know that the hypotenuse of a 45-45-90 triangle is equal to times the length of a leg.
So, in your problem the hypotenuse = (5) = 5. Another way to solve the problem is to use the Pythagorean theorem, but that is a longer way to solve it.

Answer:
7) C
8) B
9) C
Step-by-step explanation:
7) sqrt[(8-8)² + (-5-7)²] = 12 units
8) y = 4x
9) y = 6 - x
Answer:
(9, 0)
Step-by-step explanation:
A pair that would represent the x-intercept has a zero as the y-variable.
Like,
(2,0)
(-9,0)
(1.5,0)
Just like for y-intercept, the x-value must be zero.
(0,5)
(0,1.5)
(0,2)
