Answer:

10.94 mm

Step-by-step explanation:

Formula to find the area of a circle is :

Area = π r²

Given that, the area of the circle is 94 mm²

<u>Now let us find the value of r ( radius ).</u>

Area = π r²

94 = π  r²

94 ÷ π  = r²

29.92 = r²

√29.92 = r

5.47 = r

<u>And now let us find the diameter of the circle.</u>

d = 2r

d = 2 × 5.47

d = 10.94 mm

Hope this helps you :-)

Let me know if you have any other quetions :-)
