Answer:
22.3 km²
Step-by-step explanation:
The formula for the area of a circle is
A = πr²
r = ½d, so
A = π(½d)² = ¼πd²
A = ¼ × π × (16/3)² = ¼ × π × 256/9 ≈ 22.3 km²
The negation isn't always true, as you can be unhappy while also not being hungry.
If 5/6 gallons covers a quarter of the house, then you would need 4 times as much paint:

Which is 20/6 gallons or 3 and 1/3 gallons
Hope this helped
