I think the correct answer from the choices listed above is option C. <span>When you make the circle bigger or smaller, it is the radius of the standard equation for the circle centered at the origin changes. Hope this answers the question. Have a nice day.</span>
X^2 = 20(40)
x^2 = 800
x = 20<span>√2
y^2 = 20(60)
y^2 = 1200
y = </span>20√3
z^2 = 40(60)
z^2 = 2400
z = 20√6
Answer: 2 2/3 (two and two thirds)
