4 days ago, Emily blew up a ballon to a radius of 5 cm. Since then the ballon has lost air and decreased by 0.5 cm each day. What is the ratio of the current volume of the ballon to the volume of the ballon 4 days ago

10 * 563.67 = 5636.7

4038

step-by-step explanation:

pleaze mark brainliest!

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
