Answer:

The area of the circle is $9 \pi\ units^{2}$ or $28.26\ units^{2}$

Step-by-step explanation:

we know that

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=6/2=3\ units$ ----> the radius is half the diameter

substitute

$A=\pi (3)^{2}=9 \pi\ units^{2}$ -----> exact value

assume

$\pi=3.14$

$A=9(3.14)=28.26\ units^{2}$

Write three fractions that are equivalent to 3 over 11 , but written in higher terms. One of them must

Alinara [238K]

Answer:

Three fractions that are equivalent to $\frac{3}{11}$ are: $\frac{6}{22}$ , $\frac{24}{88}$ and $\frac{144}{528}$ .

Step-by-step explanation:

Equivalent fractions are set of fractions in which when simplified, they have the same answer.

Given: $\frac{3}{11}$

i. multiply the numerator and denominator of $\frac{3}{11}$ by 2,

= $\frac{3*2}{11*2}$ = $\frac{6}{22}$

i. multiply both the numerator and denominator of $\frac{6}{22}$ by 4,

= $\frac{6*4}{22*4}$ = $\frac{24}{88}$

ii. multiply the numerator and denominator of $\frac{24}{88}$ by 6,

= $\frac{24*6}{88*6}$ = $\frac{144}{528}$

So that;

$\frac{3}{11}$ = $\frac{6}{22}$ = $\frac{24}{88}$ = $\frac{144}{528}$ .

Three fractions that are equivalent to $\frac{3}{11}$ are: $\frac{6}{22}$ , $\frac{24}{88}$ and $\frac{144}{528}$ .
