Answer:
You can spell RADAR in twelve ways through the diagonal A
The arc length by definition is given by:
S = r * theta
Where:
R: radius
Theta: central angle
For this case we have that the arc length is:
S = (30/180) * 9 * pi
S = (3/2) pi
Answer:
The length of the arc shown in red is:
S = (3/2) pi

Let's solve for y.<span><span>4<span>2x</span></span>=y</span>Step 1: Multiply both sides by x.<span>2=<span>xy</span></span>Step 2: Flip the equation.<span><span>xy</span>=2</span>Step 3: Divide both sides by x.<span><span><span>xy</span>x</span>=<span>2x</span></span><span>y=<span>2x</span></span>Answer:<span>y=<span>2<span>x</span></span></span>
