Horace measured a circular lid and found d, the diameter, was 8 inches and C, the circumference, was 25 inches. Which expression represents an approximate value for pi?
Answer:
pi = 3.125
Step-by-step explanation:
We are given;
Diameter; d = 8 inches
Circumference; C = 25 inches
Formula for circumference of a circle is;
C = πd
We are trying to find the value for pi(π)
Thus; π = C/d
π = 25/8
π = 3.125
