The diameter of a roller is 84 cm and it's length is 120 cm. it takes 500 complete revolutions to move once over to level a playground. find the area of playground in m².

we are given

diameter=84cm

so,

radius =r=42cm

height=h=120cm

we know that

shape of roller is always in cylinder form

now, we can find surface area of cylinder

now, we can plug values

we know that

In one rotation , it covers area is 31667.25395 cm^2

There are 500 rotation

so, total area =

total area =

now, we need to change that area into m^2

we know that

now, we can multiply both sides 15833626.975

we get

so,

Area of playground is .............Answer

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
