18 greater than or equal z
You change the sign because the negative number becomes positive on the other side.

A circle of a certain radius has an area which is numerically 5 times the value of the circumference. What is the radius of the

patriot [66]

We have been given that a circle of a certain radius has an area which is numerically 5 times the value of the circumference. We are asked to find the radius of the circle.

We know that area of circle with a radius of r units is $\pi r^2$ .

We know that circumference of a circle is $2\pi r$ .

5 times the value of circumference would be $5(2\pi r)=10\pi r$ .

Now we will equate 5 times circumference with area as:

$\pi r^2 = 10\pi r$

Let us solve for r.

$\pi r\cdot r = 10\pi r$

$\frac{\pi r\cdot r}{\pi r}=\frac{10\pi r}{\pi r}$

$r=10$

Therefore, the radius of the circle would be 10 units.

To which subsets of real numbers does the following number belong? square root of 30

LenaWriter [7]

In order to determine which subset it belongs, we must rewrite

$\sqrt(30)$

$\sqrt(30)=\sqrt(2\times \times 3 \times 5)$

$\Rightarrow \sqrt(30)=\sqrt(2 \times 3\times 5)$

$\Rightarrow \sqrt(30)=\sqrt(2) \times \sqrt(3) \times \sqrt(5)$

All these three numbers are irrational numbers, hence their product is also irrational

<h2> $\Rightarrow \sqrt(30)$ </h2><h2>belongs to the set of irrational numbers</h2>
