Answer:

Radius = 5 inches

Step-by-step explanation:

1) We have to use the equation for the area of a circle to find the radius of the circle.

Area of a circle = πr^2

2) Plug in the information we already know, i.e., the area.

25π = πr^2

3) Cancel out the π on each side.

25 = r^2

4) Take the square root of 25

r = $\sqrt{25\\}$

r = 5

5) The radius is 5 inches.

What are the values of the variables in the triangle below?

harkovskaia [24]

Answer:

D) x=9 ; y=3√(3)

Step-by-step explanation:

$Sin(30)=\cfrac{y}{6\sqrt{3} }$

$\cfrac{18y}{6\sqrt{3}}=18\sin \left(30^{\circ \:}\right)$

$\sqrt{3}y=9$

$\cfrac{\sqrt{3}y}{\sqrt{3}}=\cfrac{9}{\sqrt{3}}$

$y=3\sqrt{3}$

$Cos(30)=\cfrac{x}{6\sqrt{3} }$

$\cfrac{18x}{6\sqrt{3}}=18\cos \left(30^{\circ \:}\right)$

$\sqrt{3}x=9\sqrt{3}$

$\cfrac{\sqrt{3}x}{\sqrt{3}}=\cfrac{9\sqrt{3}}{\sqrt{3}}$

$x=9$

Therefore, x=9 and y=3√(3)
