Answer:
Step-by-step explanation:
Let x is the length of the square side.
We know: the two figures have the same area
<=>
= π
(r being radius)
<=> x =
r
perimeter square = 4x = 4*r*
perimeter circle = 2*r*π
<=> 390 = 4*r*
+ 2*r*π
<=> r = 29.16
=> perimeter square = 4*29.16*π
=> perimeter circle = 58.32π
Answer:
8r.
Step-by-step explanation:
If we substitute 3 into all of these equations, we get
8(3) which equals 24
6(3) which equals 18
9(3) which equals 27
7(3) which equals 21
8r is the one that equals 24 when 3 is substituted.
