Answer:
b = √32
Step-by-step explanation:
The Pythagorean theorem tells you the relation between the side lengths is ...
2² + b² = 6²
b² = 36 -4 = 32
b = √32

This radical can be simplified by removing a square from under the radical.
We know that the area of a circle in terms of π will be πr². However the area with respect to the diameter will be a different story. The first step here is to find a function relating the area and diameter of any circle --- ( 1 )
For any circle the diameter is 2 times the radius,
d = 2r
Therefore r = d / 2, which gives us the following formula through substitution.
A = π(d / 2)² = πd² / 4
<u>Hence the area of a circle as the function of it's diameter is A = πd² / 4. You can also say f(d) = πd² / 4.</u>
Now we can substitute " d " as 4, solving for the area ( A ) or f(4) --- ( 2 )
f(4) = π(4)² / 4 = 16π / 4 = 4π - <u>This makes the area of circle present with a diameter of 4 inches, 4π.</u>

Answer:
Therefore the Final Solution is x = 2 and y = 7
i.e (2 ,7)
Step-by-step explanation:
Given:
...............Equation ( 1 )
...............Equation ( 2 )
..............Equation ( 3 )
To Find:
x = ?
y = ?
Solution:
Substituting Equation ( 3 ) in Equation ( 1) we get
Now Substituting x = 2 in Equation ( 3 ) we get
Therefore the Final Solution is x = 2 and y = 7
i.e (2 ,7)
