Answer:
Circumference is (with no approximation) 2π * 8 but assuming π is 3.14 the circumference is 25.13
The area is (with no approximation) π*16 but assuming π is 3.14 the area is 50.27
Step-by-step explanation:
Circumference is 2πr or πd meaning that your circle is (with no approximation) 2π * 8
Area is πr^2 meaning that it is π*4^2 which equals π*16 without approximation. Assuming π is equal to 3.14 it is
