6pi is the radius
diameter = 9 ftradius = 3 ftC = 2pir = 2(pi)(3) = 6pi ≈ 18.85 ft
the question makes no sense? 3 yards doesnt have a circumfernce. Only Circles have circumfernes ( the perimeter of a circle ) BUT..in case you want a cirlce of radius 3 yards, then it's circumference is 6Pi, and if instead you diameter is 3, than it is 3Pi.

This is true -APEX
it equals 6pi
6pi is the radius
6pi = 18.85 (rounded)
pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
diameter = 9 ftradius = 3 ftC = 2pir = 2(pi)(3) = 6pi ≈ 18.85 ft
C = 2 pi r C = 2xpix3cm C = 6pi cm C = 18.8495559 cm

The rule for the circumference of a circle is:C = 2piR, where R is the radius.So if the circumference (C) is 12, then:12pi = 2piRDivide both sides by 2:6pi = piRDivide both sides by pi,R = 6

Endothermic reaction.
It would be a catabolic reaction or decomposition reaction.
Formation reaction.
