The gcf of two numbers less than or equal to 12 is 2. Their LCM is 20.What are the numbers?

bixtya [17]

We know:

$LCM(a,\ b)=\dfrac{ab}{GCF(a,\ b)}$

We have

$GCF(a,\ b)=2,\ LCM(a,\ b)=20,\ a\leq12,\ b\leq12$

Substitute:

$20=\dfrac{ab}{2}\qquad|\cdot2\\\\ab=40$

$40=1\cdot40=2\cdot20=4\cdot10=5\cdot8$

Only 4 and 10 meet the requirements of the question.

--------------------------------------------------------------------

40 and 1 NOT, because 40 > 12

20 and 2 NOT, because 20 > 12

5 and 8 NOT because GCF(5, 8) = 1

Find the area of a circle with a diameter of \color{green}{4}4start color green, 4, end color green. Either enter an exact answe

Oxana [17]

Answer:

the area of the circle is 4π

Step-by-step explanation:

The computation of the area of the circle is shown below:

As we know that

The area of the circle = πr^2

where

diameter = 4

So radius = diameter ÷ 2

= 4 ÷ 2

= 2

Now the area of the circle is

= π × 2^2

= 4π

hence, the area of the circle is 4π
