Answer:
<h2>22 meters.</h2>
Step-by-step explanation:
It's important to notice that the area is circular, which is defined by

Replacing given values and solving for r, we have

But, the diameter is twice the radius, so

Therefore, the diameter is 22 meters.
9 divided by 3 is 3
3 minus 2 is 1
1 divides by 1 is 1
9/3=3
3-2=1
1/1=1
I hope this helped
Answer:
3.49 radians
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle. We know s and r and need to calculate Ф.
From s = rФ we get Ф = central angle = s/r
Here, that central angle Ф is (31.4 cm) / 9 cm = 3.49 radians
Answer: 20 miles
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
x^2 = a^2 + b^2
Where x is the hypotenuse of the triangle (in this case the distance between Dayton and Belleville) and a and b are the other sides.
Replacing with the values given:
x^2 = 16^2 + 12^2
x^2 = 256+144
x^2 = 400
x = √400
x = 20 miles
