Well, I suppose, but only in the sense that it is hard to change the direction of the axis of rotation. A bicycle is also stabilized by the rotation of the tires. The faster the spin, the more torque is needed to turn or tip the wheels. (torque = rate of change of angular ...

fn = a + d(n-1) f(7) = a + 6 d = 72 f(10) = a + 9 d = 90 so 3 d = 90 - 72 = 18 d = 6 a + 6*6 = 72 a = 36 so our sequence is f(n) = 36 + 6(n-1) f(2) = 36 + 6(1) f(2) = 42

well, I suppose the length of the rectangle (L = d = diameter is twice the width (r = radius) so 2 r + 4 r = 30 6 r = 30 r = 5 cm 2 pi r/2 = 5 pi of course the base of the semicircle is another 2r or 10 cm so if that counts we have 5 pi + 10 for the entire perimeter of the ...
