Answer:

(b) √55

Step-by-step explanation:

The right triangles in this geometry are all similar, so the ratio of long side to short side is the same:

y/5 = 11/y

y² = 55 . . . . . . multiply by 5y

y = √55 . . . . . take the square root

And x=4√5 by looking at ratios of short side to hypotenuse.

The circumference of a circle is 6 inches. What is the area of the circle?

Lubov Fominskaja [6]

Answer:

(B) 9π in²

Step-by-step explanation:

I’m going to assume that by 6 inches you meant 6π inches.

If the circumference of a circle is 6π inches, then it’s radius will be half of 6 (because the circumference of a circle is $2\pi r$ ).

$6\div2=3$

So the radius is 3.

Now that we know the radius, we can find the area by using the equation $\pi r^2$ .

$\pi 3^2\\\pi9\\9\pi$

Hope this helped!
