Well, to find a circles circumference, C=D* pi. if d =10, 10 * pi (or 3.14 for now), C= 31.4. so the answer is false. It is measuring distance as a radius instead of diameter.
This is a simple subtraction problem. To find out how many more plastic trains there were than wooden trains, subtract the number of wooden trains from the number of plastic trains.
41 (plastic) - 23 (wooden) = 18 more plastic than wooden
The unit rate is 1:50. I did the math but I’m just guessing because you didn’t put any choices
Answer:
C = 60pi cm or approximately 188.4 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
C = 2* pi * 30
C = 60 pi
We can approximate pi by 3.14
C is approximately 60*3.14 or 188.4
