Answer:
Step-by-step explanation:
The perimeter of a circle is 2πr
r here is 7 so the perimeter of the full circle is 14π which is 43.9822972
But you only have half a circle, so 43.9822972 / 2 = 21.991148.
But now you have to add the 14 cm to it to close the half circle, so 21.991148 + 14 = 35.991148 or 36 cm
Answer:
Each team ran (scored) 90 runs.
Step-by-step explanation:
Don't really know how to explain it but I'll show what I did.
First I understood that for every 9 runs team A runs, team B runs 7.
This means that if we multiply 9 by a number, we have to multiply 7 by the same number.
Now that we understand this, we need to figure out a number that when multiplied with 7 and 9 then added together equals 1440.
I'm pretty sure there was an easier way to do this but I did it the way I know will for sure give me the right answer and that's estimating that mystery number until you get it. Sorry my explanation wasn't the best.
Work:
9 x 90 = 810
7 x 90 = 630
810 + 630 = 1440
