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
Now let us find the value of r ( radius ).
Area = π r²
94 = π r²
94 ÷ π = r²
29.92 = r²
√29.92 = r
5.47 = r
And now let us find the diameter of the circle.
d = 2r
d = 2 × 5.47
d = 10.94 mm
