An oocyte is an immature reproductive cell found in many sexually reproducing organisms. A crawfish oocyte has a radius of approximately 1\, \text{mm}1mm1, start text, m, m, end text, while a human oocyte is much smaller and has a radius of about 0.05\, \text{mm}0.05mm0, point, 05, start text, m, m, end text.
Surface area of a sphere: A = 4πr^2A=4πr
2
A, equals, 4, π, r, squared
Assuming both cell types are perfectly spherical, how many times larger is the surface area of a crawfish oocyte compared to the surface area of a human oocyte?
