Please do 1-9 show work as well if possible!

I’ll do about half becuase I don’t feel like doing them all but explanation wil be provided

Step-by-step explanation:

Explanation: For a circle, to find the diamenter multiply the radius by 2 and by pi or in this case 3.14

Diameter= 2r*π

Or

Diameter= D*π

D is just diameter

For area its

Area= Π*r^2

R is radius, if a diameter is given then just divide the diameter by 2 to find the radius

1) R= 2.5mm: Work= 5/2=2.5

2) Try it on your own

3) D= 34cm: Work= 17*2=34

4) Try On your own

5) A= 132.67cm^2: Work= 13/2=6.5 ; 6.5^2=42.25 ; 42.25*3.14=132.67

6) A= 38.47m: Work= 3.5^2=12.25 ; 12.25*3.14=38.47

Try to figure the rest
