Answer:
320 crayons per class
Step-by-step explanation:
the school bought 25 boxes...each containing 64 crayons.....so that a total of (25 * 64) = 1600 crayons.

so ur answer is 3/4
** fractions are improper if the numerator is bigger then the denominator.
and when the numerator and denominator are the same, the fraction equals 1
R=12cm
circumference=2×pi×r
=2×3.14×12
=75.36cm
area = pi×r^2
=3.14×12×12
=3.14×144
=452.16cm^2
