Acoin dealer is having paper wraps made to go around a stack of coins. the coins have a diameter of 12 mm, and the dealer states that the paper should be exactly 36 mm wide, or 3 times the diameter, to go around the coins. is the coin dealer correct?

No, not enough paper.

Should be 3.14 instead of 3.

The circumference will be 12 times pi.

(12)(3.14) = 37.68

step-by-step explanation:

b and c

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
