Answer:
1) C=2355 2) C=1570 3) C=157 4) C=40.82
Step-by-step explanation:
We use formula to find the Circumference of circle is :
i) C=(PI)d ii) C=2(PI)r
1. d=750 m
C=(PI)d = (3.14)(750)=2355
2. d=500 kg
C=(PI)d=(3.14)(500)=1570
3. r=25 cm
C=2(PI)r
=2(3.14)25=157
4. r=6.5 m
C=2(PI)r
=2(3.14)(6.5)
=40.82
