chord ab =chord CD in a circle with centre o .op perpendicular to CD
and oq perpendicular to CD if op= 4 cm then find length of oq
Answers
Answer:
The length of PQ is 7 cm.
Step-by-step explanation:
Given information: The radius of the circle is 5 cm. AB=8 cm and CD = 6 cm. OP⊥AB, OQ⊥CD.
From the below figure it is noticed that triangle AOP and COQ are right angled triangle.
Perpendicular from the center always a chord bisector.
Use Pythagoras theorem in triangle AOP,
AO^2=AP^2+OP^2
5^2=(4)^2+OP^2
25-16=OP^2
OP^2=9
OP=3
