Solution

Solution :-
Diameter of front wheel = 63 cm
Radius = 63/2 cm
Circumference of front wheel = 2πr
⇒ 222/763/2
⇒ 2772/14
Circumference of front wheel = 198 cm
Diameter of rear wheel = 1.54 m or 154 cm
Radius = 154/2
= 77 cm
Circumference of rear wheel = 222/777
⇒ 3388/7
Circumference of rear wheel = 484 cm
Area of front wheel = πr²
⇒ 22/763/263/2
⇒ 87318/28
Area of front wheel = 3118.5 cm²
Area of rear wheel = 22/77777
⇒ 130438/7
Area of rear wheel = 18634 cm²
