Answer:
28°
Step-by-step explanation:
Angle on the circumference is half the angle at the centre
c = ½(56)
c = 28°
Volume of a sphere = 4/3pi*r^3
diameter/2 = radius
Radius = 12/2 =6
Volume of sphere = 4/3pi*6^3 = 288pi
The first choice because angle ABQ equals 90 degrees
Convert 6 to the fraction 18/3.
Since the fractions 18/3 and 1/3 have the same denominator, we add their numerators to calculate them.
Subtract on both sides.
Combine and to get .
Subtract 19x from both sides.
Convert 5 to the fraction 15/3.
Since the fractions 15/3 and 19/3 have the same denominator, we add their numerators to calculate them.
Multiply both sides by -4/3, the reciprocal of -4/3.
Multiply -4/3 by -4/5 (to do this, multiply the numerator by the numerator and the denominator by the denominator).
Length of diagonal, l = √(a² + b²)
l = √(130² + 200²)
l = √(16900 + 40000)
l = √56900
l = 238.537
After rounding-off to the nearest whole number, it would be 239.
In short, Your Answer would be Option D
