Fraction division is basically multiplication of a reciprocal.
For example (1/4)/(1/8) = (1/4)x(8/1)=2
Multiplication of the answer and the piece that divides (in this case 2 x 1/8), you should get the piece that is being divided (in this case 1/4). If that is correct, then your division is correct.
Answer:
31.4 in
Step-by-step explanation:
I must assume that you meant "10-inch pizza," which implies a diameter of 10 inches. The formula for the circumference of a circle when the diameter is known is C = πd , so here:
C = π(10 in) = 10π in, or roughly 31.4 in.
