A=Pier^2

a=pie2.5^2

a=19.63

A=Pier^2

a=pie2^2

a=12.57

19.63 - 12.57

=7.07

B

Given:

The equation is .

To find:

Whether the given equation is a direct variation or inverse variable.

Solution:

Direct variation: y is directly proportional to x.

Inverse variation: y is inversely proportional to x.

Where, k is the constant of proportionality.

We have,

Divide both sides by x.

It is in the form of inverse variation.

Since and it is inverse variation, therefore the correct option is (d).
