Question

A circle with center Q is shown in the figure below.

R
(a) Name a radius:
0
7
(b) Name a diameter:
(c) Name a chord:
(d) If the length of QT is 7 units,
what is the length of RS?
X
units

Answer 1

(a) A radius of the circle can be named as QR.

(b) A diameter of the circle can be named as RS, as it passes through the center Q.

(c) A chord of the circle can be named as QS, as it's a line segment that joins two points on the circle.

(d) If the length of QT is 7 units, and QR is a radius of the circle, then the length of RS is also 7 units because RS is a diameter of the circle, and a diameter is twice the length of a radius.
