Answer:

Step-by-step explanation:
The equation of a circle is given by
, where
is the center of the circle and
is the radius of the circle.
From the diagram, we can find the following:
- the radius of the circle is 4
- the center of the circle is located at (1,6)
Thus, we have:

Answer:
20
Step-by-step explanation:
Side of the square = hypotenuse of triangle = √(4² + 2²)=√(16 + 4)=√(20)
Area of a square = (side)² = (√20)² = 20 units²
Sequence: 2 + 1 + 1/2 + 1/4 + 1/8 + ...
Explanation:
Here Given Sum to Infinity

Identify following
Solve:


The sum of this infinity series is 4
You would have to convert subtraction to addition. so it would be -5/18 + 1/4.
-5/18+1/4 is -0.028 rounded up
