A = pi × r²
3.14 x 2²
3.14 x 4
A = 12.56636 ≈ 12.56
hopefully this helps u and if u know the formula to solve it, it is super easy
I'm fairly sure it's C - even as a prediction, if you add (4x2) and (2x2) it's 12 - and the closest is thirteen, adding on the fractions.
It would be: 5/6 / 30/60
We can re-write it as: 5/6 * 60/30
= 1/1 * 10/6
= 5/3
In short, Your Answer would be 5/3 or 1 2/3 or 1.67
Hope this helps!
