The area of a circle can be expressed by the formula a = πr^2 where r is the radius of the circle. express the radius in terms of the area of the circle

Step-by-step explanation:

dont get it though but ill try

so the formula for the circle is a=Pier squared

so that means the we just say out radius is 8 so square 8 you get 64

so you answer is 64 if the radius is 8

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
