Answer:
diameter: 50
radius: 25
area: 625 Pi (1,962.5)
Step-by-step explanation:
1. circumference= diameter times Pi
2. circumference= (x) times 3.14
3. 157=3.14x
4. 157/3.14=3.14x/3.14
5. 50=x
6. 50= diameter
7. diameter/2= radius
8. 50/2= radius
9. 25=radius
10. radius times radius times Pi= area
11. 25 times 25 times 3.14= area
12. 1,962.5= area
