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)

Simplify.<br> (-3.9) + (6.01) - (-7.423)<br> -5.513.<br> 2.487.<br> 9.533.

lianna [129]

First, since we must follow PEMDAS, we need to do the operation that is first, which is addition.

-3.9 + 6.01 ← Adding a negative means subtracting, then giving the sign of the bigger number.

So now we solved those and we got this answer: 2.11

Now, we need to subtract and re-write the expression.

2.11 - (-7.423) = 2.11 + 7.423= 9.533

Ok....so now we have our final answer, and we have the choices above.

The only answer that matches ours is the last one.

Final answer: 9.533

Hope I helped ^_^
