Answer:

15.21

Step-by-step explanation:

In order to find the area, you must find the radius first.

The diameter (4.4) divided by 2 = radius (2.2)

The area of a circle is pi times the radius squared (A = \pi r^{2}).

In this situation, r, or radius =2.2.

A = \pi 2.2^{2}

\pi2.2^{2}= the area, 15.2053084434.

By rounding to the nearest hundredth, you get 15.21. The second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

Find a rational number and an irrational number that are between 9.5 and 9.7.
IRISSAK [1]
So to better understand this question, let us define rational and irrational numbers first. Rational numbers are those numbers that can be written in fractions. On the other hand, irrational numbers are those numbers that cannot be written as fractions and the common example of it is pi. So, the rational number that is between 9.5 and 9.7 would be 9.6. This can be written as 9 and 3/5 or 48/5. And the irrational number would be <span>9.562359123571283578. Hope this answer helps.</span>
