Question

Select the correct answer.Frogs lay spherical eggs that are 1.2 millimeters in diameter. Nutrients are absorbed through the egg's surface. What is the approximate area of a frog egg's surface?A. B. C. D.

Answer 1

4.52 square millimeters.

Explanation:

The surface area of a sphere is given by the following equation:

`A=4\pi\cdot r^2`

We know the diameter of the egg, the radius is equal to half the diameter, therefore the radius is 0.6 millimeters, we substitute and calculate the surface area:

`\begin{gathered} A=4\pi\cdot(0.6)^2 \\ A=1.44\pi \\ A=4.52mm^2 \end{gathered}`

Therefore the surface area is 4.52 square millimeters.
