The equation to calculate the surface area is 4πr²
The equation to calculate volume is 4/3πr³
<u>Explanation:</u>
The shape of the cell is in the form of a sphere.
The surface area of the cell can be calculated by the formula =
The volume can be calculated by the formula =
Given,
The surface area of the cell is 24μm²
4πr² = 24μm²
Radius, r can be calculated from the above equation.
The volume of the cell is 8μm³
4/3πr³ = 8μm³
We can calculate radius, r from the above equation.
Therefore, the equation to calculate the surface area is 4πr²
The equation to calculate volume is 4/3πr³
