Answer 1

Answer:

your answer is

Step-by-step explanation:

Let external point be B. OA be radius of circle. 

Let external point be B. OA be radius of circle. Given: 

Let external point be B. OA be radius of circle. Given: OB=12.5 cm

Let external point be B. OA be radius of circle. Given: OB=12.5 cmAB=12 cm

Let external point be B. OA be radius of circle. Given: OB=12.5 cmAB=12 cmIn right triangle, AOB, by Pythagoras Theorem,

Let external point be B. OA be radius of circle. Given: OB=12.5 cmAB=12 cmIn right triangle, AOB, by Pythagoras Theorem,OB2=AB2+OA2

Let external point be B. OA be radius of circle. Given: OB=12.5 cmAB=12 cmIn right triangle, AOB, by Pythagoras Theorem,OB2=AB2+OA2AO2=OB2−OA2=12.52−122=12.25

Let external point be B. OA be radius of circle. Given: OB=12.5 cmAB=12 cmIn right triangle, AOB, by Pythagoras Theorem,OB2=AB2+OA2AO2=OB2−OA2=12.52−122=12.25∴AO=3.5 cm

Diameter=2(AO)=2(3.5)=7 cm

Let external point be B. OA be radius of circle. 

Given: 

OB=12.5 cm

AB=12 cm

In right triangle, AOB, by Pythagoras Theorem,

OB2=AB2+OA2

AO2=OB2−OA2=12.52−122=12.25

∴AO=3.5 cm

Diameter=2(AO)=2(3.5)=7 cm
