Step-by-step explanation:

Formula:

$\pi {r}^{2}$

(Note, the radius of a circle can be calculated by dividing the diameter by 2)

$\pi {7}^{2}≈154$

Find the gcf of the following<br><br> 4x^4y^3 and 24x^3y^2

Effectus [21]

Answer:

The greatest common factor (gcf) of $4x^{4}y^{3}$ and $24x^{3}y^{2}$ is 4 x³ y²

Step-by-step explanation:

The greatest common factor of algebraic terms is:

The greatest common factor of the numbers
Least exponent of the same variables

Ex: The greatest common factor of 8 x² and 12 x³ is 4 x² because:

The factors of 8 are 1, 2, 4, 8 and the factors of 12 are 1, 2, 3, 4, 6, 12

The common factor of them are 1, 2, 4 and the greatest on is 4

The greatest common factor of x² and x³ is x²

So the gcf of 8 x² and 12 x³ is 4 x²

∵ The terms are $4x^{4}y^{3}$ and $24x^{3}y^{2}$

∵ The factors of 4 are 1, 2, 4

∵ The factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24

∴ The common factors of them are 1, 2, 4

∵ The greatest one is 4

∴ The greatest common factor of 4 and 24 is 4

∵ The greatest factor of $x^{4}$ and x³ is x³

∵ The greatest factor of y³ and y² is y²

∴ The greatest common factor of $4x^{4}y^{3}$ and $24x^{3}y^{2}$ is 4 x³ y²
