Yes, if the slope is correct, he can just subtract 4 from his answer.
For example, let's use 10 for x. In the equation he originally had, we would have
y=3.5(10)+16=35+16=51
In the actual equation, we would have
y=3.5(10)+12=35+12=47
Taking 51-4 would give us the same result.
Area of circle formula: πr^2
Since the radius is half of the diameter, divide 38 by two.
r = 19 miles
A = π(19)^2 = π(361)
Now, substitute in 3.14 for π
A = 3.14(361) = 1133.54

Answer: 1133.54 sq. miles</h2>
Answer:
9. 40°
10. 50°
11. 270°
12. 310°
Step-by-step explanation:
m∠BPC = 40° because it is complementary to ∠APB, which is 50°.
Arc AB is 50° because it will be equal to the central angle, which is 50°.
Arc ADC is 270° because it will be equal to the central angle, which is 270°.
Arc ADB is 310° because it will be equal to the central angle, also 310°.
You have to make sure the number is 650,000 or above, and 749,999 or under
