Step-by-step explanation:

(6+r)^2 = 81 + r^2

36 + 12r+ r^2 = 81 + r^2

12r = 81-36 = 45

r = 15/4 = 3.75

Gre4nikov [31]

Answer: The required two number will be 247 and 248.

Step-by-step explanation:

Since we have given that

Number of people at the Cineplex on last Saturday=1486

Number of theaters are there=6

Number of people in each theatres is given by

$\frac{1486}{6}=247.66$

So it must lie between 247 and 248.

As the number of people in each theatre is 247.66 so , it may be between 247 and 248.

So, the required two number will be 247 and 248.

Let AB be a chord of the given circle with centre and radius 13 cm.

Then, OA = 13 cm and ab = 10 cm

From O, draw OL⊥ AB

We know that the perpendicular from the centre of a circle to a chord bisects the chord.

∴ AL = ½AB = (½ × 10)cm = 5 cm

From the right △OLA, we have

OA² = OL² + AL²

==> OL² = OA² – AL²

==> [(13)² – (5)²] cm² = 144cm²

==> OL = √144cm = 12 cm

Hence, the distance of the chord from the centre is 12 cm.
