Answer: 39.4 m^2

Explanation:
The area of a circle is pi * radius squared. The diameter is 4 m, the radius is half the diameter so for the equation the radius is 2 m.

Pi times 2 is 6.28 (remember that pi is roughly 3.14), then square that sum of 6.28.

6.28^2= 39.4384

The answer is 39.44 but the answer must be rounded to the nearest tenth, 39.4384 is 39.4 rounded to the nearest tenth.

Are the fractions 3/9, 3/10, 3/11, and 3/12 in order from least to greatest

Cerrena [4.2K]

Answer:

The fractions $\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}$ are not in order from least to greatest.

Step-by-step explanation:

Given order of fractions from least to greatest:

$\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}$

To check if the fractions are in correct order.

Solution:

The fractions given have same numerators but different denominators.

For fractions the higher the denominator the lower is the value of that fraction.

Thus, in the given list the least value fraction will be the fraction with the greatest denominator which is $\frac{3}{12}$ and the greatest value fraction will be the fraction with the least denominator which is $\frac{3}{9}$

So, the order of the fractions from least to greatest is not correct. Instead the order is from greatest to least.

The correct order from least to greatest should be:

$\frac{3}{12},\frac{3}{11},\frac{3}{10},\frac{3}{9}$ .
