Answer:
Area of the sector = 47.52π
Step-by-step explanation:
Area of the sector of the circle;
A = ∅ / 360 * πr²
We know that;
∅ = 120
r = 12
So now we can substitute;
A = (120 / 360) * π(12)²
A = 0.33 * 144π
A = 47.52π
Hope this helps!
Answer: 1 and 21/100
Step-by-step explanation: Using the place value chart, we can see that 1.21 means 1 unit, 2 tenths, and 1 hundredth.
