For full circle area is π * R² [here R = radius],
for a sector of circle with angle β, area will be = (β/2) * R², β is in radian,
here let β = 22.5° = (π * 22.5/180) = π/8 radian,
now [(π/8)/2] * R² = 9π, [π/16] * R² = 9π
R² = 9 * 16 = 144,
R = √144 = 12 m
Answer:
x = 50
Step-by-step explanation:
When two secants intersect in the interior of a circle, the angles formed are the average of the arc an angle and its vertical intercept. In this case, our angle, 73, should be the average of x and 96. We can translate this to an equation and solve:
x + 96 = 146
x = 50

ANSWER
The correct choice is C.
EXPLANATION
The perimeter of a rectangle is given by;
P=2(w+l)
For the first rectangle, the perimeter is;
P=2(8+4)=24
For the second rectangle, the perimeter is
P=2(8+8)=32
For the third rectangle, the perimeter is
P=2(8+12)=40
The correct choice is C
