Answer: 254.35ins
Step-by-step explanation:
Circumference of a circle = 2πr or πd.
Given the area of the circle = 56.52ins. To find the area of the circle, we first need to find the radius of the circle first by making r the subject of the formula.
2πr = 56. 52
r = 56.52
----------
2π
where π = 3.14
Now put this in r above and solve
r = 56.52/2 x 3.14
= 56.52/6.28
= 9ins.
Now to find the area of the circle substitute for r in the equation of the area of the circle below
Area of circle = πr²
= 3.14 x 9²
= 3.14 x 81
= 254.35ins
