Find the circumference of 15in and round your answer to the nearest tenth
Are you talking about the diameter being 15 in?
If so:
C = pi times d
C = 3.14 times 15
If you were talking about a radius, then you have to double the radius to get the diameter.
To find the circumference of a circle, you need to use the formula:
C = 2πr
In this case, the radius (r) is half of the diameter, which is given as 15in. So, to find the radius, divide the diameter by 2:
r = 15in / 2 = 7.5in
Now, you can use the formula to find the circumference:
C = 2π(7.5in)
C ≈ 15π in
C ≈ 15(3.14) in (using an approximate value for π)
C ≈ 47.1 in
Rounding the answer to the nearest tenth, the circumference of a circle with a diameter of 15in is approximately 47.1in.
