Imagine the area is 360 degrees, or $2\pi$ radians.

You would multiply it by (3/8) to get your answer.

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

A person walks 1/2 miles trail in 1/6 hour what is their average speed as a unit rate

tatiyna

Answer:

6miles/hour

Step-by-step explanation:

Speed = Distance/time

So speed is: $\frac{\frac{1}{2}}{\frac{1}{6}}$

You will get 6/2 from this so you get 6miles/hour

Which interval notation represents the set of all numbers less than or equal to -6 or greater than or equal to -2

Alik [6]

Answer: 1≤x<12

Step-by-step explanation:

The values that are greater than or equal 1 but less than 12 are values ranging from 1 to 11 i.e {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}. Note that 1 is included because the number is greater than or equal to 1 (1 included) and less than 12(12 not included).

x≥1 and x< 12

if x≥1, it means 1≤x

combining both inequality

1≤x and x<12

1≤x<12

The interval notation that represent the set S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} will be given as S = {x: 1≤x<12}
