I don’t understand the equation. What am I solving for?
Answer: 12.56 / 4 = 3.1416 =9.4248
Step-by-step explanation: pi by the 2 squared gives u the area of all the circle but u need to fin 3/4 of the circle so divide by 4 and the result of the dividion x 3 gives u the answer
2/15 so 13.3% ?
I’m not entirely sure if this is right but I think it’s getting there...
Answer:
They add up to equal 90 degrees.
A=πr^2s/360 multiply both sides by 360
360A=sπr^2 divide both sides by πr^2
s=360A/(πr^2)
