Answer:
x = 3 units
SV = 2 units
Step-by-step explanation:
In
QR and ST are chords such that:
QR = ST = 4
That is both the chords are equal in measure.
Equal chords are at equal distance from the center of the circle. Therefore,
VZ = UZ
4x - 6 = 6
4x = 6 + 6
4x = 12
x = 12/4
x = 3 units
Since, perpendicular dropped from the center of the circle bisects the chord.

Answer:342
Step-by-step explanation:100+130+112=342
Answer:
a = 157.7536pi
Step-by-step explanation:
area = pi*circumference²
a = pi*12.56² = 157.7536*pi
however, if pi just equals 3.14:
probably around 495.346304
