give me a math problem about circumference, radius, diameter, and pi
Sure! Here's a math problem involving circumference, radius, diameter, and pi:
Find the circumference of a circle with a diameter of 12 inches, rounded to the nearest whole number. (Use the value of pi as 3.14)
38
That's incorrect. Let's calculate it step by step:
Given:
Diameter = 12 inches
Radius = (Diameter / 2) = (12 / 2) = 6 inches
Pi (π) = 3.14
To find the circumference (C):
C = 2 * π * Radius
Substituting the given values:
C = 2 * 3.14 * 6
C = 37.68 inches
Rounded to the nearest whole number, the circumference is 38 inches, so your answer is correct! Well done!
