The scientists determined the mean diameter of muscle fibres in trained mice usingan optical microscope to examine sections of muscle tissue. The circular area (πr2)of one field of view was 1.25 mm2. The diameter of this area was equal to thediameter of 15 muscle fibres.Using this information, calculate the mean diameter in µm (micrometres) of musclefibres in this section of tissue.

this should be a simple maths question, how do you get the radius of 1.25 and then times it by two. then you just convert mm into micrometres

Yep, I figured it out about how you need to divide by pi first then square root it which is where I kept going wrong. Thanks anyway
