Circles have the equation (x-h)²+(y-k)²=r² with the center at (h,k) and radius r
so if you bring the equation into this form you can read everything off

x²+y²-4=0
x²+y²=4
(x-0)²+(y-0)²=2²

so the radius r=2
h=0,k=0 which means the center is at (0,0)

densk [106]
Let volleyball be v and let basketball be b.

v : b = 4 : 7,      b = 21

v : 21 = 4 : 7

v/21 = 4/7

7*v = 4*21

v = 4*21/7

v = 4*3

v = 12

Volleyballs are 12
