Answer:
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
