Answer» Diameter of the park = 66mRadius of the park = 66/2 = 33mRadius of park including path = 33m + 4m= 37m area of path = area of park including path - area of park = π(37)^2 - π(33)^2 = π(37^2-33^2) = π(37-33)(37+33) m^2 = (22/7) × 4 ×70 =880 m^2 cost of turtling the path = 880× 2.5= Rs 2200 hit like if you find it useful

Answer»

Diameter of the park = 66mRadius of the park = 66/2 = 33mRadius of park including path = 33m + 4m= 37m

area of path = area of park including path - area of park = π(37)^2 - π(33)^2 = π(37^2-33^2) = π(37-33)(37+33) m^2 = (22/7) × 4 ×70 =880 m^2

cost of turtling the path = 880× 2.5= Rs 2200
