Question
(a) Name a diameter: QR (b) Name a radius: SV (c) Name a chord: UT (d) If the length of SV is 6 units,what is the length of RQ? units
Solution
(a) A diameter is a straight line passing from one side to another through the center of a circle or sphere. In this case, QR is the diameter.
(b) A radius is a straight line from the center to the circumference of a circle or sphere. In this case, SV is the radius.
(c) A chord is a straight line connecting two points on the circumference of a circle or sphere. In this case, UT is the chord.
(d) The length of a diameter is twice the length of a radius. So if the length of SV (the radius) is 6 units, then the length of RQ (the diameter) is 2 * 6 = 12 units.
