The circle above has a radius of 7 cm. What is the area of the circle?

1 answer:

8 0

$A=\pi r^2$
A - area, r - radius

$r=7 \ [cm] \\
\pi \approx 3.14 \\ \\ A=3.14 \times 7^2=3.14 \times 49=153.86 \ [cm^2]$

The area is 153.86 cm².

Name three different complex fractions that simplify to 1/4

Ksenya-84 [330]

If we want a complex fraction, we can take a simple fraction and multiply it by some other fraction. in out case, these can be obtained if we mupltiply 1/4 by some other fraction for example:

1/2:
$\frac{ \frac{1}{2} }{ \frac{4}{2} }$

Or we could expess one of the numbers as a fraction:
$\frac{1}{ \frac{4}{1} }$

Given the box plot, will the mean or the median provide a better description of the center? (1 point)
