Answer in explanation
Step-by-step explanation:
In this question, we would be examining the validity of some statements on the number π(pi)
π Is a whole number?
This is wrong, π is a fraction of 22 to 7 parts I.e 22/7
π Is double the radius?
This is wrong. It is the diameter that is double the radius
π Is approximately 3.14?
This is correct to an extent. The actual value in decimal is around 3.142857142857143 which makes the 3.14 somehow correct
π represents the ratio of the circumference of the circle to the diameter?
This is correct.
Mathematically, circumference C = π * diameter D
Hence C/D = π
π Is approximately 22/7?
This is correct. This is the ratio used for π
Answer:
• Pi is approximately 3.14.
• Pi represents the ratio of the circumference to the diameter
• Pi is approximately 22/7
Step-by-step explanation:
From the options given:
A. Pi is a whole number:
Pi is equivalent to 3.141592654. Therefore, pi is not a whole number.
B. Pi is double the radius
Pi is not double the radius of a circle. Pi is a constant.
C. Pi is approximately 3.14.
In some cases, pi can be approximated as 3.14 instead of 3.141592654.
D. Pi represents the ratio of the circumference to the diameter.
Circumference of a circle, C = 2 × pi × radius
= 2 × pi × D/2 = pi × Diameter
Pi = circumference/Diameter
E. Pi is approximately 22/7
22/7 = 3.142857143
This is also a correct approximation.
