Rajeev walks around a circular park of area 88704 sq. m. How long will he take to walk 10 rounds at a speed of 4.5 km per hour

Answer 1

From area of circle r^2= 4032*7 = 7*576*7 =. 24*24*7*7. So r= 24*7=168. perimeter of circle is 2πr = 2*22/7*168 =2*22*24 = 2*528 = 1056m So, perimeter = 1.056km So total distance = 1.056*10 = 10.56. A/Q time, t = total distance / speed = 10.56/4.5 =2.34 So, answer is 2.34 hour. please mark me as brainliest
