Find the circumference of a circle with a radius of 5.5 in. Use 3.14 for and round your answer to one decimal place.
17.3
To find the circumference of a circle, you can use the formula:
Circumference = 2 * π * radius
Given that the radius is 5.5 in and π is equal to 3.14, we can substitute these values into the formula:
Circumference = 2 * 3.14 * 5.5
Now, let's calculate the circumference using a calculator or by hand:
Circumference = 2 * 3.14 * 5.5 = 34.54
Rounding the answer to one decimal place, the circumference of the circle with a radius of 5.5 in is 34.5 inches.
C = pi * d
The radius is half the diameter, so the diameter is 11 in.
C = 3.14 * 11
C = ?
