Diameter = 1.4 m r = d/2 r = 1.4/2r = 0.7m curved surface area of cyclinder = 2 * 22/7 * r^2 = 2 * 22/7 * 0.7 * 0.7 = 8.8 m^2 No of revolution = 5 Therefore = 8.8 * 5 = 44 m2

Heya,
Given:-
Height = 2m
Diameter = 14m
Radius = 14/2 = 7m
Revolution = 10
To find:-
Area covered by the roller.
Solution:-
Distance covered by the roller = 2πrh
Distance covered by the roller = 2 × 22/7 × 7 × 2
Distance covered by the roller = 2 × 22 × 2
Distance covered by the roller = 44 × 2
Distance covered by the roller = 88m^2
Area covered by the roller = 10 × 88
Area covered by the roller = 880m^2
Hope my answer helps you

Diameter = 14cm
Radius = D/2 = 14/2 = 7cm
Height = 2m = 200cm
CSA of Roller = 2πrh
= 2×22/7×7×200
= 44×200 = 8800cm²
Area covered by roller in 1 revolution = 8800cm²
Therefore,
Area covered by roller in 10 revolution = 8800×10 = 88000cm²
Radius = D/2 = 14/2 = 7cm
Height = 2m = 200cm
CSA of Roller = 2πrh
= 2×22/7×7×200
= 44×200 = 8800cm²
Area covered by roller in 1 revolution = 8800cm²
Therefore,
Area covered by roller in 10 revolution = 8800×10 = 88000cm²
