Answer:
7/10 pi (radians)
Step-by-step explanation:
The formula for sector area is (angle * r^2)/2
140pi = angle*r^2/2
multiply both sides by 2
280pi = angle * r^2
r = 20 cm (substitute)
280pi = angle * (20)^2
280pi = angle * 400
Divide both sides by 400
7/10 pi = angle
Answer:
-60 if you meant all of them its -180
Step-by-step explanation:
First you would add all the marbles together because you need to know how many are in the bag in total.
7 + 8 + 5 = 20
Next you simply put the number for blue over the total
8 / 20
And there's your answer.
Your answer would be -624 because 1-210-3= -212 then 3 times -212 +12= -624
