Question

find the radius of the circle with centre p if the the chord is equal to 8 cm and its distance from the circumference is 2 cm.
​

Answer 1

Answer:

10

Step-by-step explanation:

perpendicular from centre to chord bisect the chord

Answer 2

OD=3 cm

AB=8 cm

Radius =OB

In △OBD

OB (2) = BD(2) +OD(2)

⟹OB (2)

=4 (2)

+3 (2)

⟹OB=5 cm

Radius - 5 cm
