Answer:

28.6 m²

Step-by-step explanation:

The measurements of the square are 4 by 4; this gives us an area of

4(4) = 16 m²

The quarter circle has a radius of 4 m. The area of a circle is given by

A = πr².

Since we have a quarter circle, we multiply this by 1/4:

A = 1/4πr²

Using 3.14 for π and 4 for r,

A = 1/4(3.14)(4²) = 1/4(3.14)(16) = 3.14(4) = 12.56 m²

Together this gives us a total area of 16+12.56 = 28.56 m².

This rounds to 28.6 m².

Step 1.

Calculate measure of angle α:

$47^o-38^o=9^o$

Step 2.

Calculate what fraction of the angle 360° is the angle α:

$\dfrac{9^o}{360^o}=\dfrac{1}{40}$

Step 3.

Calculate the circumference of the Earth (circle):

$C=2\pi r\to C=2\pi\cdot4000=8000\pi\ mi$

Step 4.

The length of arc is equal 1/40 of the circumference:

$\dfrac{1}{40}C=\dfrac{1}{40}\cdot8000\pi=200\pi\ mi$

$\pi\approx3.14\to\dfrac{1}{40}C\approx200\cdot3.14=628\ mi$

What is the interquartile range of this set of data? 15, 19, 20, 25, 31, 38, 41

Irina18 [472]

First, you have to find the median, which is the number in the middle: 25

Then cut the data in half by the median, so your new data sets are
15,29,20
and
31,38,41

Now you find the median of both of those sets, which is 29 and 38.

The interquartile range is the difference between the numbers, so 38-29 = 9.
