<u>Given:</u>

The circle has a diameter of 30 cm and a chord of 10 cm is drawn.

Radius of the circle = 15 cm

Half of the chord = 5 cm

We need to determine the distance of chord from the center of the circle.

<u>Distance of chord from the center of the circle:</u>

Let us use the Pythagorean theorem, to find the distance between the center and the chord.

Let d denote the distance between the center and the chord of the circle.

Thus, we get;

15^2=d^2+5^2

225=d^2+25

200=d^2

Taking square root on both sides, we get;

14.14=d

Thus, the distance between the center and the chord of the circle is 14.14 cm.

Hence, Option A is the correct answer.

Jackie sold 48 pints of lemonade at her stand. How many quarts of lemonade did she sell? (1 quart = 2 pints)
Rufina [12.5K]
OK.  Since One quart= 2 pints,  divide the number of pints (48) by 2.
48/2=24
24 is the answer for the number of quarts.
