Give a circle C(O;4cm) and a point A such that OA=2 cm, then
A on (C)
A inside (C)
A outside (C)
The diameter is the shortest chord in a circle
The 2 circles A(M; 5) and B(N;3) where MN= 2 are disjoint internally
Given the two circles C(O; r) and C(O'; r') where OO'=12 If the circles are tangent externally and r is double of r' than
r=10 and r'=2
r'=8 and r=4
r'=4 and r=8
Given the two circles (C ) and (C’) are internally tangent, and OO’= 9 cm. Calculate R’, if R is twice the radius of (C’) decreased by 3 cm.
R'=3 and R=12
R=7 and R'=2
Find the correct answer
