Step-by-step explanation:
Area of circle = 88704 m²
Radius = ?
Area of circle = πr² = 88704 m²
Radius of park = 168 cm
So, circumference of park = 2πr
Circumference of park = 1056 m
He walka 10 rounds around park so multiple it by 10
1056 x 10 = 10560 m
This area is in metre so change it in kilometre
distance travelled by ram = 10.56 km
Speed of ram = 4.5 km/hr
Time taken = ?
He takes 2.34 hr to complete his walk
