You need to add up three things:
- two sides of 60" each (60*2=120")
- the perimeter of the upper semicircle (3.14*27/2=42.412")
- the perimeter of the lower semicircle (3.14*27/2=42.412")
After addition:
120+42.412+42.412=204.823"
I hope you got
the idea!
12 to the second power is equal to 144
(12 x 12)
Answer:
6 packages.
Step-by-step explanation:
If they are $3 each, and you only have $18, divide 18 by 3, which gives you 6.
Total number of ways to make a pair:
The first player can be any one of 7 . For each of those . . .
The opponent can be any one of the remaining 6 .
Total ways to make a pair = 7 x 6 = 42 ways .
BUT ... every pair can be made in two ways ... A vs B or B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.
If every pair plays 2 matches, then (21 x 2) = <em><u>42 total matches</u></em> will be played.
Now, is that an elegant solution or what !
53 is the answer, I think
