????????? wotz the quesshun ????????
did teech giv yu sumthun tu find, evaluzte, solv for, kompute, derive?????
Sins the 2 points mark the "diameter", that impli...sumthun about serkel
points: (-2,-1) & (2,1)
deltax=2-(-2)=4
deltay =1 -(-1)=2
length av diameter=root(deltax^2 +deltay^2)
2^2=4 & 4^2=16
sum=20
diameter=root(20)=4.472135955
