Final answer:
To find the radius of a circular region where the ground leveling cost Rs 4928 at Rs 2 per square meter, one must calculate the area by dividing the cost by the rate and then use the area formula for a circle to solve for the radius.
Step-by-step explanation:
The student has been asked to find the radius of a circular region given the total cost of leveling the ground and the rate per square meter. The cost of leveling is Rs 4928 at a rate of Rs 2 per square meter. To find the radius, we first need to determine the area of the circle by dividing the total cost by the rate (4928 ÷ 2 = 2464 square meters). The formula for the area of a circle is A = πr², where A is the area and r is the radius. Rearranging the formula to solve for the radius gives us r = √(A ÷ π). Substituting the values, we get r = √(2464 ÷ 3.1415927), which gives us the radius of the ground.
