<span>A = pi*r^2
ATriple = pi*(3r)^2 = 9*pi*r^2 = 9 A

Triple the radius, increase the area by a factor of 9.</span><span>

i hope this has helped!</span>

The area is multiplied by 9 (I'm pretty sure)

Lloyd solves the equation 24x + 18(x – 2) = 216 for x. Some of his steps are shown.

ANTONII [103]

Answer:

24+18x-36=216

-12+18x=216

18x=216+12

18x=228

x=228/18

x=30/3

A person is on the outer edge of a carousel with a radius of 20 feet that is rotating counterclockwise around a point that is ce

<h2>Answer:</h2>

$\boxed{(5(-\sqrt{2}+\sqrt{6}),5(\sqrt{2}+\sqrt{6}))}$

<h2>Step-by-step explanation:</h2>

The origin of the coordinate system is the center of the circle. So we have an angle that measures $5\pi/12=75^{\circ}$ . so the x-coordinate and y-coordinate can be found, by using trigonometry as follows:

$x=20cos(5\pi/12)=5\sqrt{6}-5\sqrt{2} \\ \\ Arranging:\\ \\x=5(-\sqrt{2}+\sqrt{6}) \\ \\y=20sin(5\pi/12)=5\sqrt(6)+5\sqrt{2} \\ \\ Arranging:\\ \\y=5(\sqrt{2}+\sqrt{6})$

Finally, the exact value of the position of the rider after the carousel rotates $5\pi/12$ radians is:

$\boxed{(5(-\sqrt{2}+\sqrt{6}),5(\sqrt{2}+\sqrt{6}))}$
