I need to simplify this

Hi there!

$3 \sqrt{54} + 2 \sqrt{24} =$
First we split up the square root into two parts.

$3 \times \sqrt{9} \times \sqrt{6} + 2 \times \sqrt{4} \times \sqrt{6} =$
Now we calculate the value of the square roots which have an integer as a solution

$3 \times 3 \times \sqrt{6} + 2 \times 2 \times \sqrt{6} =$
Multiplying the integers gives us our next step.

$9 \sqrt{6} + 4 \sqrt{6} =$
And finally we add up the roots.

$13 \sqrt{6}$

Art [367]

Answer:

18.85 inches.

Step-by-step explanation:

We have been given that the radius of a smaller circle 3 inch. We are asked to find the circumference of smaller circle.

We know that circumference of a circle is equal to $2\pi r$ , where r represents radius of circle.

$\text{Circumference of smaller circle}=2\pi (3\text{ inches})$

$\text{Circumference of smaller circle}=6\pi\text{ inches}$

$\text{Circumference of smaller circle}=18.84955592\text{ inches}$

$\text{Circumference of smaller circle}\approx 18.85\text{ inches}$

Therefore, the circumference of smaller circle is approximately 18.85 inches.
