2.50 = pi r2. i really need on this problem.

r = 0.8923

Step-by-step explanation:

pi = 3.14

2.50 = 3.14 * r^2                      Divide by 3.14

2.50/3.14 = 3.14*r^2 / 3.14

.7962 = r^2                               Switch

r^2 = 0.7962                             Take the square root of both sides.

sqrt(r^2) = sqrt(0.7962)            

r = 0.8923                                 Answer  

I don't know where you are getting stuck. Maybe it's finding the square root. You can do that on almost any calculate by

Perhaps it is the value of pi. The usual approximation is 3.14. Take that as your value.

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
