the answer is 2,220
you first aline 185 × 12 like so 185
× 12
then you need to multiply everything
<span>1) 20 cm by 20 cm by 6 cm
2) 40 cm by 30 cm by 2 cm</span>
<span>You did not include the equations that you want to assess whether they can be used to solve for the radius (r).
Likely, the equation of the circumference, C = 2*Pi*r is included, if so => r = C / (2*Pi).
If you round Pi to 3.14, the equation may be written r = C / 6.28.</span>
