The circumference covered by a radar signal can be represented by the expression 400π miles. What is the approximate length of t

goldfiish [28.3K]

Answer:

127 if it says to use 3.14, 200 if it does not ask to use 3.14

Step-by-step explanation:

C= $2\pi r$

Substitute C for 400

400=2*r

400=2r

divided both sides by 2

Answer is 200

This figure is 1/4 of a circle.

drek231 [11]

For this case we have that by definition, the perimeter of a circle is given by:

$C = 2 \pi * r$

Where:

r: It is the radius of the circle.

According to the figure, it is observed that the radius of the circle is 2. Then:

$C = 2 \pi * 2\\C = 2 * 3.14 * 2\\C = 12.56 \ in$

Let's remember that we have a quarter circle:

$C = \frac {12.56} {4}\\C = 3.14$

We round and we have that the correct option is $3.1 \ in$

Answer:

Option A

The attached figure is the image that completes the question

Explain how you know 21/100 is greater than 1/5

Nataly_w [17]

This problem can be solved using equivalent fractions. The first step in resolving this problem is to realize that fractions are best compared when they both have the same denominator. In this case, I will choose to make that common denominator 100. There is no need to rewrite the fraction $\frac{21}{100}$ as the denominator for this fraction is already 100. The fraction $\frac{1}{5} =\frac{20}{100}$ . This is achieved by multiplying both the numerator and denominator by 20. Now that the two fractions have the same denominator, we can easily see that $\frac{21}{100}$ is greater than $\frac{1}{5}$ because it is greater than its equivalent fraction.
