Answer:

arc length = 4π units

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

= 2πr × $\frac{90}{360}$

= 2π × 8 × $\frac{1}{4}$

= 2π × 2

= 4π units ← exact answer

Answer:

OC=48

RK=100

Step-by-step explanation:

We can use proportions to find both OC and RK.

$\frac{OK}{KY} =\frac{OC}{RY}$

$\frac{12}{24} =\frac{OC}{96}$

$24OC=1152$

$OC=48$

$\frac{KC}{RK} =\frac{OK}{KY}$

$\frac{50}{RK} =\frac{12}{24}$

$12RK=1200$

$RK=100$

<em>To solve for a variable, you just need to isolate the variable to one side.</em>

For this, just divide both sides by r and <u>your answer will be $\frac{d}{r}=t$ </u>

For this, divide both sides by nR and <u>your answer will be $\frac{PV}{nR}=T$ </u>

Firstly, multiply both sides by T: $AT=FV-OV$

Next, subtract FV on both sides of the equation: $AT-FV=-OV$

Lastly, multiply both sides by -1, and <u>your answer will be $-AT+FV=OV$ </u>

Firstly, multiply both sides by 1000: $1000C=Wtc$

Lastly, divide both sides by tc and <u>your answer will be $\frac{1000C}{tc}=W$ </u>
