Answer:
Measure of CD is also 16.5 units
Step-by-step explanation:
Given the figure in which distance from centre to chord is 4.4 units
we have to find the value of q
As radius from centre to the chord perpendicularly bisect the chord
⇒
From the figure, it can be seen that the distance from center to the chord is equal that is in measure.
∴ Using the property that if the distance from the center to the chord is equal, then the chords are always in equal in measure.
As measure of AB is 16.5
⇒ Measure of CD is also 16.5 units
Hence, option (C) is correct.

Answer:
7
Step-by-step explanation:
The diagonal is the hypotenuse of the right triangle with legs 7
Use Pythagoras' identity to solve for the diagonal d
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
d² = (7)² + (7
)²
= 147 + 147
= 294 ( take the square root of both sides )
d = = 7
≈ 45.37 ( to 2 dec. places )
