Question

Can Someone plz help? Thx

Answer 1

1) C=2355 2) C=1570 3) C=157 4) C=40.82

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
