Answer:
49π
Step-by-step explanation:
Circle area: πr^2
Since A to C is 14, and they're both in the center, A to B and B to C will both be 7 as a radius.
Since we know the radius, we can put it in the formula, πr^2.
We only need to solve for one circle, since both circles are the same. By solving the circle, we will put in 7 for the radius, giving us π7^2, which is 49π.
Is there a picture to go along with this??
11,340 I believe. 5% of 8400 is 420. 420*7=2940 2940+8400=11340
Answer:
Step-by-step explanation:
5x + 2 = 4x - 9
Collecting like terms
5x - 4x = -9 - 2
x = -11
1 is <span>y = 15x, in 9 years he will have saved $13,500
2 is </span><span>x2 − 4x − 21
