Answer:
5995 hugs
Step-by-step explanation:
This is a combination problem: we want to make groups of two monkeys, where a pair of monkey 1 and 2 is the same pair of monkey 2 and 1 (it is the same hug). So, if the total number of monkeys at the zoo is 110, we have a combination of 110 choose 2:
C(110,2) = 110! / (2! * (110-2)!) = 110 * 109 / 2 = 5995
So the total number of hugs is 5995
To find the circumference you use c = pi d. Radius * 2 = Diameter
c = 3.14(36)
c = 113.04 in. square.
Only one triangle because 70+30+80=180 and 1 triangle has in total 180°
