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
First you’d have to multiply 5 & 22, 5x22=110 and 110x5=550
So it’s 550
(10+6) / 8+2-4=0
10 plus 6 equal 16, divided by 8 plus 2 minus 4 equal 0
