The formula for radius is 
.
First we need to see what 8*π is, put it in your calculator and you will get . So now we know the exact circumference, so now put that into the equation to find the radius.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY!

The answer is D. because after the 25 years the value increases by 66$ which makes the card valued at 90.95 once you add the original value. Thus making the card less than 100$
Answer:
1. x = 1, y = -3
2. x = 3, y = 4
Step-by-step explanation:
Here, we want to solve the sets of simultaneous equations;
a) -y = 5x-2
-3y = -5x + 14
substitute 1 into ii
3(5x-2) = -5x + 14
15x - 6 = -5x + 14
15x + 5x = 14 + 6
20x = 20
x = 20/20
x = 1
from;
-y = 5x - 2
y = -5x + 2
y = -5(1) + 2
y = -3
b) -2y = -6x + 10
2y = x + 5
Substitute ii into i
-(x + 5) = -6x + 10
-x - 5 = -6x + 10
-x + 6x = 10 + 5
5x = 15
x = 15/5
x = 3
2y = x + 5
2y = 3 + 5
2y = 8
y = 8/2
y = 4
