THat is B
{2,4,6,8,10}
Add 5 to both sides. Then 8x > -6, and x > -3/4 (answer)
Answer: the area is 20 square centimeters.
Step-by-step explanation:
The area of an arc of angle x in a circle of radius r is:
A = (x/3.14)*3.14*r^2 = x*r^2
here we have x = (4/5)*3.14 and r = 5cm
Then the area is:
A = (4/5)*(5cm)^2 = 20cm^2
The answer is 5 and 2/5. Hopefully it is correct!
