Question

How many square centimeters of silver foil would Maya need to cover the model completely?

150.9

201.1

603.3

402.2

Answer 1

A=4pi*r^2

area of sphere's surface

and because we dont want full sphere, we just divide it to two


4*pi*16=201.06193


201.06193 / 2 = 100.530965

Answer 2

Then we add the surface of the circle

Answer 3

so the answer is 150.9?
