The circumference, or perimeter, of a circle can be found by multiplying its diameter by 3.14. what is the circumference of a circle that has a diameter of inch? express your answer as a decimal.

circumference is 159.512mm

Step-by-step explanation: the circumference of a circle is given by

C=2πr

Given that r is 1inch

1inch =25.4mm

Therefore

C=2*3.14*25.4

C=159.512mm

In geometry, the circumference of a circle is the distance around it. That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment. Since a circle is the edge of a disk, circumference is a special case of perimeter

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
