I guess it may be but iam not sure
Finding an area of a circle: 3.14*r^2
But they gave us diameter instead of radius, to find radius: r= D÷2 so 84 ÷2= 42.
Area: 3.14*42^2
Area: 3.14* 1764
Area: 5538.96cm^2

4/10 = 12/20 since 4/10 = 10/20
The coefficient is 2 (it is always the number before the variable)
1.0 2.39 3.3 4.-17 5.. 15 6. -24 7. 43 8. 39 9. -11 10.-17
Area of a circle is = PI x r^2
Area = 27 PI
This means the radius would be the square root of 27:
√27 = 3√3
The answer is F.
