Question

The radius of a circle is 2x-3 what is the function for the area of the circle

Answer 1

The function for the area of the circle with radius 2x-3 is A = π(4x2-12x+9).

Step-by-step explanation:

The function for the area of a circle is given by the formula A = πr2. In this case, the radius of the circle is 2x-3. Substituting this value into the formula, we get:

A = π(2x-3)2

Simplifying:

A = π(4x2-12x+9)

Therefore, the function for the area of the circle is A = π(4x2-12x+9).

Answer 2

A = pi * r^2

= pi * (2x^-3)^2

= pi * 2^2 * (x^-3)^2

= pi * 4 * (x^-6)

= 4*pi * x^-6
