The area of the sector that has a central angle of 120 degrees and radius of 8 units is 64π / 3 units²
<h3>Area of a sector</h3>
The area of a sector is defined as follows:
area = ∅ / 360 × πr²
where
- r = radius
- ∅ = central angle
Therefore,
r = 8
∅ = 120°
Hence,
area of the sector = 120 / 360 × π × 8²
area of the sector = 1 / 3 × π × 64
area of the sector = 64π / 3 units²

Answer:
Step-by-step explanation:
in 6 years we know that it will be half, because that's what "half life" means
in 3 years it's only loses 1/2 * 1/2 = 1/4 of it's mass
in 1 year it's only loses 1/6 * 1/2 = 1/12 of it's mass
from that we can make the formula that
current weight of radium = Wr
Mass of radium orginal = Mo
year of time = t ( must be in years, not days, months or weeks )
Wr = (1/12)*t* Mo
