This can't be found... when you get it to work, I will be happy to help!
plz help urgent
Since the radius is 28mm, we know that the diameter is 56mm.
Therefore, the length of the rectangle will be 56mm. Knowing this, I bet you can work out the area of the rectangle :D
Hope this helped!
If we connect the centers of the circles, we will have an equilateral triangle with sides of 2R = 2(28) = 56mm
The height of this triangle, H, can be found as
tan 60° = H /(1/2 side length of the triangle)
√3 = H / 28
28√3 = H
Then the height of the rectangles = R + height of triangle + R = 2R + 28√3 = 2R + 28√3 = 56 + 28√3
And the width of the rectangle = 4R = 4*28 = 112
So....the area of the rectangle =
(56 + 28√3) (112) ≈
11703.711 mm^2 ≈ 11700 mm^2
