If you would like to know which is the correct unit of measurement to use when figuring out how many yards each child would run in the race, you can calculate this using the following steps:
80 yards * 2 + 60 yards * 2 = 160 + 120 = 280 yards
The correct measurement would be A. yards.
8x+15=7
answer: x= 1 hope this help
Answer:
A
Step-by-step explanation:
the slope of A is 1/2 which is greater than that of B
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.
