Question

I have a question on calculating the following with the given data.

Given:
day 1 - bacteria colony appears circular with a radius 1cm and depth 2mm but the radius is observed to vary between 0.96cm to 1.05cm

day 2 - the radius = 1.5cm +/- 0.03cm and depth 3.4mm +/- 0.3mm

calculate the follow
a) volume of each day
b) rate of growth of the volume of the bacteria colony
c) estimate the uncertainty in the radius of bacteria colony on day 1
d) calculate the uncertainty in the volume of colony on day 1 and day 2

I decided to convert all my measurements to mm
