A cylindrical roller with diameter 77 cm and height 1 m is used to level a rectangular park with dimensions22 × 11 . Find the number of revolutions required to level the park.

 The number of revolutions required to level the park is 100.

Step-by-step explanation:

Given : Diameter of roller = 77 cm

Then radius of roller : r =

Height = 1 m = 100 cm

Curved surface area of roller =

Dimensions of park = 22 × 11 m

Then Area of park =

Now , the number of revolutions required to level the park = (Area of park) ÷ (Curved surface area of roller )

Hence, the number of revolutions required to level the park is 100.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
