True or false? if a radius of a circle intersects a chord, it is perpendicular to that chord.

False

Step-by-step explanation:

If a  radius of circle intersect a chord then it is not necessary that it bisect the chord.

If the radius bisects the chord then it will be perpendicular to chord.

But, if does not bisect the chord then it won't be perpendicular to that chord.

The radius is perpendicular to chord when it bisects that chord .

Hence, if a radius of a circle intersects a chord, it is not  perpendicular to that chord.

Answer : False

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
