A rotating wind turbine has a diameter of about 116 feet and its circumference is about 364 feet. A smaller model of the turbine has a circumference of about 13 feet. What will the diameter of the model
be? If necessary, round to the nearest whole number. The diameter of the model will be about feet.

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
