Answer:
Area: 7850 square cm
Perimeter: 314 cm.
Step-by-step explanation:
The area is [tex]\pi r^{2}[/tex]. With r=50, [tex]\pi 50^{2}[/tex]=2500π which is about (2500)(3.14)=7850.
The perimeter is [tex]2\pi r[/tex] which is the same as (diameter)(π). The diameter is 100, so [tex]100\pi[/tex] which is about (100)(3.14)=314.
