Circle A has a circumference of

lilavasa [31]

#Circle A

$\\ \bull\tt\longmapsto 2πr=16$

$\\ \bull\tt\longmapsto 2(3.14)r=16$

$\\ \bull\tt\longmapsto 6.28r=16$

$\\ \bull\tt\longmapsto r=\dfrac{16}{6.28}$

$\\ \bull\tt\longmapsto r=2.6units$

#Circle B

$\\ \bull\tt\longmapsto πr^2=25$

$\\ \bull\tt\longmapsto r^2=\dfrac{25}{π}$

$\\ \bull\tt\longmapsto r=\sqrt{\dfrac{25}{π}}$

$\\ \bull\tt\longmapsto r=\dfrac{5}{\sqrt{π}}$

$\\ \bull\tt\longmapsto r=\dfrac{5}{\sqrt{3.14}}$

$\\ \bull\tt\longmapsto r=\dfrac{5}{1.74}$

$\\ \bull\tt\longmapsto r=2.94units$

Circle B has bigger radius

In 3/4 cup of oatmeal, that is 1/10 of the recommended daily value of iron. What faction of the daily recommended value of iron

Nastasia [14]

Answer:

recommended value of iron is $\frac{2}{15}$

Step-by-step explanation:

In 3/4 cup of oatmeal, that is 1/10 of the recommended daily value of iron

The ratio of cup of oatmeal to the value of iron is

$\frac{\frac{3}{4}}{\frac{1}{10} } =\frac{30}{4}$

Let x be the recommended value of iron for 1 cup of oatmeal

Make a proportion

$\frac{oatmeal}{value} =\frac{oatmeal}{value}$

$\frac{30}{4} =\frac{1}{x}$

cross multiply

$30x=4$

$x=\frac{4}{30}$

$x=\frac{2}{15}$

recommended value of iron is 2/15
