Answer:

6cm

Step-by-step explanation:

to find the diameter of a circle whose circumference is = 18 .84

the formula for finding the circumference of a crcle = πd

18.84 = πd

note π = 22/7 or 3.14

so,

18. 84 = 3.14 × d

divide both sides by 3.14

18.84/3.14 = 3.14d/3.14

6cm = d

therefore the diameter of the circle whose circumference is 18.84 is equal to 6cm

A linear equation determines a line in the xy-plane.<br><br> A. True<br> B. False

Artemon [7]

Answer:

True, A linear equation determines a line in the xy-plane.

Step-by-step explanation:

A linear equation is in the form of Px + Qy = R where P , Q and R are constants.

Let us take an example 2x +3y = 6

When we plot the above equation in graph we get a line in xy plane.(as shown below) Since, there are two variables, x and y, then will it be possible, only on the xy plane.

It is also clear from the graph that linear equation shows the relation between x and y axis. Thus, it is true to say a linear equation determines a line in the xy-plane.
