A thin silver disc of diameter 10 cm costs #3 300. What is the cost per m2

AAAaannndd the bot gets it wrong yet again!

3300/(25π) #/cm^2 * (100cm/1m)^2 = 420,169 #/m^2

The cost per m2 is #33,000. To calculate this, first calculate the area of the disc. The area of a circle is A = πr2, where r is the radius of the circle. The radius of the disc is 5 cm, so the area is A = π(5 cm)2 = 78.54 cm2. The cost per m2 is then 3 300 / 78.54 cm2 = 33,000.
