Areas Related To Circles
We have given AB = 4m and circumference of semicircle with radius OA as.
We are asked to find the area between the two semi-circles.
For that we will first find OA.
Now we will substitute
Now we will find OB.
Now we will find the area between two semi-circles as given below,
Therefore, area of the path is 339.43 m2.
Now we will find the cost of gravelling the path.
Therefore, cost of gravelling the path is Rs 509.14.
Now we wi...
