Answer:
principle= 6000
time =9 years
rate = 7%
so,
compound interest = p((1+r/100)^t. -1)
= 6000((1+0.07)^9 -1)
=6000(1.84-1)
=6000*0.84
=5040
Answer:
-11-12h
Step-by-step explanation:
Answer: r = 4cm/θ
Step-by-step explanation:
For a circle of radius R, the perimeter is:
P = 2*pi*R
Now, if we have an arc with an angle θ, the cord of this arc is:
C = (θ/2*pi)*2*pi*R
Where you can see that if θ = 2*pi (this is the full circle) we have the perimeter of the circle.
In this case, we can see that the cord for an angle θ is 4cm, then:
C = 4cm = (θ/2*pi)*2*pi*r = θ*r
Now we can solve this for r:
r = 4cm/θ
