When the area in square units of an expanding circle is increasing twice as fast as its radius in linear units

r = 1/π

Step-by-step explanation:

Here we have

Area of a circle given as

Area = πr²

Where:

r = Radius of the circle

When the area of the circle is expanding twice as fast s the radius we have

However,

and

Therefore, we have

Cancelling like terms

Therefore, .

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
