The area of any circle is equal to
, where r is the radius.
We know that the diameter is 12. The radius is always half of the diameter, so the radius of our circle must be 6.
Substitute 6 for r in our equation and simplify.
π6² = π6×6 =
36π in²
A. False
B. True
C. False
D. True
407 over 5 but it also has to be simplified
Answer:
<h2>1/4</h2>
Step-by-step explanation:
Area of a circle is given as πr² and its circumference is expressed as 2πr.
If the babylonians determined the area of a circle by taking it as equal to the square of the circle’s circumference then;
Area of circle = (circumference of a circle)²
πr² = (2πr)²
πr² = 4π²r²
Dividing both sides of the equation by πr² we have;
The value of π this yields is 1/4
