➷ The formula for circumference is [tex]\pi d[/tex]
1) [tex]\pi d = 31.4[/tex]
Divide both sides by [tex]\pi[/tex]
d = 9.99 (consider this to be 10)
Half this to find the radius
10/2 = 5
It would be figure B.
2) [tex]\pi d = 37.68[/tex]
Divide both sides by [tex]\pi[/tex]:
d = 11.99 (consider this to be 12)
Divide by 2 to find the radius:
12/2 = 6
It would be figure C.
3) area = [tex]\pi r^2[/tex]
[tex]\pi r^2 = 153.86[/tex]
r^2 = 48.97515909
r = 6.998 (consider this to be 7)
It would be figure D
4) [tex]\pi r^2 = 113.04[/tex]
r^2 = 35.98174
r = 5.998 (consider this to be 6)
It would be figure C.
5) radius = diameter / 2
radius = 3
[tex]\pi (3)^2 = 28.27433[/tex]
It would be option C
