What the area of a circle with the diameter of 10 kilometers

Given:

Given that the diameter of the circle is 10 kilometers.

We need to determine the area of the circle.

Radius of the circle:

The radius of the circle can be determined using the formula,

Substituting d = 10, we get;

Thus, the radius of the circle is 5 kilometers.

Area of the circle:

The area of the circle can be determined using the formula,

Substituting r = 5, we get;

Thus, the area of the circle is 78.5 square kilometers.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
