The area of circle B is 121 times greater than the area of circle A. The radius of circle B is 44. What is the radius of circle

xxMikexx [17]

<em>Formula:</em>
$\bigg( \dfrac{radius_1}{radius_2} \bigg)^2 = \dfrac{area_1}{area_2}$

<em>Plug in the values:</em>
$\bigg( \dfrac{r}{44} \bigg)^2 = \dfrac{1}{121}$

<em>Simplify LHS:</em>
$\dfrac{r^2}{1936} = \dfrac{1}{121}$

<em>Multiply by 1936 on both sides:</em>
$r^2 = \dfrac{1936}{121}
$

<em>Simplify RHS:</em>
$r^2 = 16$

<em>Square root both sides:</em>
$r = 4$

Answer: The radius is 4 units. (Answer B)

Ari’s teacher says he may have his report grade based on either the mean or the median of his last six test scores.

stepan [7]

To find the mean you: <span>add up all the numbers, then divide by how many numbers there are. So the mean for these numbers would be: 84%

To find the median: You put the numbers in order (From least to greatest), and then find the number exactly in the middle. Here it is an even amount of numbers. No problem, just add the two numbers in the middle and then divide by 2. The answer here is: 84%
