If the area of a circle measures 9/4 π cm 2, what is the circumference of the circle in terms of π?

Given that the area of the circle = .

Now question says to find the circumference of the circle.

Before finding circumference, we need to find the radius of the circle so let's use formula of area of circle which is :

plug the given value of area

take square root of both sides

Now we can use formula of circuference to find the circumference of given circle

Circumference

Circumference

Circumference

Circumference

Hence final answer is cm.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
