Javion · Answer 1

The surface area of the spherical biscuit is calculated through the equation,

A = 4πr²

We are given with one surface area, that is the amount of wrapper per biscuit.

200.96 = 4πr²

The value of r from the equation is 5.65 cm. A diameter is twice the value of the radius. Thus, the answer is 11.3 centimeters.
