Point p is the center of two concentric circles. pq = 4.2 and ps = 8.2. mc027-2.jpg is tangent to the smaller circle and a chord of the larger circle. what is length to the nearest tenth?

The length of the chord is 14.1 units.

Step-by-step explanation:

Given : Two concentric circles with common center Point P.

Smaller circle with radius, PQ = 4.2 unit

Bigger circle with radius, PS = 8.2 unit

Tangent to the smaller circle is a chord of the larger circle.

To find: Length of the chord , RS

Solution:

Perpendicular drawn from the center of the circle to the chord bisect the chord. So,

SQ = QR

In given figure, ΔPSQ

(Pythagoras theorem)

RS = SQ + QR = 7.042 units+7.042 units = 14.084 units ≈ 14.1 units.

The length of the chord is 14.1 units.

check the picture below.

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
