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:

To fing the diameter of a circle when given the circumfrence we use the formula of



Answer:
B
Step-by-step explanation:
To find the distance we need to add the numbers:
2 - (-3/4) = 2 + 3/4
Answer:
8.06 ft or
ft
Step-by-step explanation:
Since Rebecca bought a square table and squares have equal sides, you can take the square root of the area of the table, which gives you
ft per side. This can be approximated to 8.06 ft.
