Final answer:
To find the cost of constructing the road around the circular park with a given diameter of 84 m and a cost of 480 Rupees per meter square, we need to calculate the perimeter of the park and multiply it by the cost per meter.
Step-by-step explanation:
The diameter of the circular park is given as 84 m. To find the cost of constructing the road around the park, we need to calculate the perimeter of the park and then multiply it by the cost per meter.
The radius of the park can be found by dividing the diameter by 2, so the radius is 42 m. Using the formula for the circumference of a circle, which is C = 2πr, we can calculate the perimeter of the park as P = 2π(42 m) = 264 m.
The cost of constructing the road would be the product of the perimeter and the cost per meter, which is 264 m × 480 Rupees/m² = 126,720 Rupees.
