Question

1) In a circle with centre O seg OP perpendicular chord AB, AB=48 cm, OP=7 cm. then find radius of the circle​

Answer 1

Answer:

23

Step-by-step explanation:

Given:

AB = 48cm

OP = 7cm

To Find:

(i) Radius

Construction:

Join OA

Solution:

In ∆OAP

By Pythagoras Theorem:

AB^2= OA^2+OP^2

24^2= OA^2+7^2

576=49+OA^2

576-49=OA^2

OA^2=529

OA=√529

OA=23

Therefore the radius of the circle is 23 cm.
