Problem

An oocyte is an immature reproductive cell found in many sexually reproducing organisms. A crawfish oocyte has a radius of approximately 1, start text, m, m, end text, while a human oocyte is much smaller and has a radius of about 0, point, 05, start text, m, m, end text.
Surface area of a sphere: 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?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
