I guess the would help you
You need to divide-4 on both sides which will get you 8.hope this helps
The answer is 3 1/3 + 2 1/3 = 5 2/3
For example #1 is 3/4 since there is no whole number but but for #3 1 and 1/8
Circumference is found with the formula
c = pi × d
d is diameter and we will use 3.14 for pi.
The diameter is the measure across the center of the circle. In the first problem, you are given the radius, so we have to multiply by 2 to get the diameter. Then we can use the formula.
12.4 in × 2 = 24.8 in (that's the diameter)
c = pi × D
c = 3.14 × 24.8
c = 77.872 inches
circumference is 77.872 inches.
Try the other problems on your own. They are just like this one. Just make sure they are giving you the diameter and not the radius. Post if you have problems.
