The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A

Answer:
4^-2=1/16
Step-by-step explanation:
When we are multiplying exponents and the bases are the same, we add the exponents
4^6 * 4^-8
4^(6+-8)
4^-2
1/16
We know that one yard is equivalent to 0.9144 meters.
We are given the number of yards = 5 (1/4) yards. To know the equivalent number of meters, all we have to do is cross multiplication as follows:
number of meters = (5 1/4 * 0.9144) / 1 = 4.8006 meters
Rounding the answer to the nearest tenth, we would get 4.8 meters
