What circular area is covered by the signal if the circumference is 754 miles?

Answer:

A =45216 miles^2

Step-by-step explanation:

We can find the radius

C = 2 * pi *r

754 = 2 * pi *r

Divide each side by 2 pi

754 /2pi = 2 * pi *r/ 2 pi

377/pi =r

Approximating 3.14 for pi and rounding the radius to the nearest mile

120 = r

Now we need to find the area

A = pi r^2

A = 3.14 (120)^2

A = 3.14 (14400)

A =45216 miles^2

Match the following reasons with the statements in the given proof. Prove that if two angles are complementary to the same angle
yulyashka [42]

1. --> d

2. --> b

3. --> a

4. --> c

1 is d because that is the only piece of information that sounds like a given.

2 is b because we know that from the given, m∠1 is complementary to m∠2 and in the first problem, m∠1 + m∠2 = 90, they are added together. The definition of complementary angles is "Two angles with measures that, when added together, equal 90 degrees". Same thing with m∠3 and m∠2.

3 is a because since both of the problems equal 90 degrees, you can just take away the 90 and put an equal sign in between the two problems because they equal the same thing.

4 is c because you are subtracting m∠2 from the problems and ending up with just m∠1 = m∠3.

Hope this helps! :)
