No u didn’t, the line is wrong. from the point -1 it should intercept (-2,-4) and (2,2)
Answer:
B) Observing how probability works with real items
Step-by-step explanation:
Just took the quiz :)
The answer to that will be the letter c , 24ft
The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.
A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π
From the statement, we know that r2=2(r1).
<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have
5 x (r1)^2 = 80
Thus,
r1 = 4 and r2 = 8
