Heyaa!!
let r be the radius of roller and h be its height
given that
D = 84 => r = 42
h = 120 cm
it says it takes 500 time of revolution to complete one round then it will be its area
ok
area of playground = 500 × 2πrh
= 500 × 22/ 7 ×42×120
= 500×31680 cm ^2
= 15840000/ 100×100 m^2
= 1584 m ^2
hope this helps u
