Question

Check my answer for medal please

Answer 1

I thought maybe A because 48/3=16

Answer 2

no.. it's not A and D at all

Answer 3

Then B because C doesnt fit.

Answer 4

because the equation of the circle is (x-h)^2+(y-k)^2=r^2 where h and k is the center, but since the equation you have is x^2+y^2 = 48 we have (0,0) as the center.. as for radius you need the square root of 48

Answer 5

try 16 x 3 and grab the square root of 16

Answer 6

16*3=48 sqrt of 16= is 4

Answer 7

yeah so you have 4 sqrt(3) as the answer... to check just take 4sqrt(3) to the second power..
