रौलर की त्रिज्या = 70/ 2 = 35

r=35m

लम्बाई h =2m

रौलर का वक्र पर्ष्ठीय छेतरफल =

2\pi \: rh

area =2×22/7 ×35×2

=440 वर्ग मीटर
total area = 50 × 440
= 22000 m

Radius of rolar = 70/2

= 35 cm

in one cycle rolar travels distance

= 2πr

= 2×22/7×35

= 220 cm

= 2.2 m

so in one round covered area = 2.2×2

= 4.4 m²

then in 50 rounds covered area

= 4.4×50

= 220 m²

hope this answer helpful u
