I need help, please and thank you. I know that you have to multiply the diameter by 2 to find the radius, but with the 9 pi, it

andrew11 [14]

Answer:

r=6

Step-by-step explanation:

The area of a circle is given by πr². Note that this uses the radius, not the diameter.

Now, one quarter of this area (ABC) is given to be 9π.

So apparently:

$\frac14 \pi r^2 = 9\pi$

If you solve this:

$\frac14 r^2 = 9$ (divide both sides by π)

$r^2 = 9\cdot4$ (multiply both sides by 4)

r = √36 = 6

so the radius is 6.

Find the value of x!!!!!!!!!!!!

Phantasy [73]

Answer:

$x=3\sqrt{7}$

Step-by-step explanation:

If a tangent and a secant connect to an exterior point of a circle, the tangent squared is equal to the product of the two segments the secant creates.

Therefore, we have:

$x^2=7 \cdot 9,\\x^2=63,\\x=\sqrt{63}=\boxed{3\sqrt{7}}$
