Answer: x=-1, y=7. 1st eqaution=-1+7=6, 2nd eqaution=7+-3=4
Answer:
11.2square feet
Step-by-step explanation:
Area of a sector = theta/360 * πr²
theta is the central angle = 80degrees
radius r = PC = 4ft
Substitute
Area of the sector = 80/360 * 3.14 * 4²
Area of the sector = 80/360 * 3.14 * 16
Area of the sector = 4,019.2/360
Area of the sector = 11.2ft²
Hence tthe area of the blue sector is 11.2square feet
Answer:
Substitute the 80°F where the F is in the equation. then just put the whole equation into your calculator. I got approximately 26.7.
Step-by-step explanation:
V=1/3 × πr²h
since H=6, R=4
V= π×(4)²×(6)/3
V=96π/3
V=32π
Note: ( we are not given the pie (π) value )
sorry i cant help on that its tricky but try 8???
