Suppose the radius of a circle is 4. what is its area?

Find the zeros of the function. write the smaller solution first, and the larger solution second f(x)= (x+6)^2-49

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed

Ineed to know the answer to this algebra question.
