Anna is making a circular rug. If the radius of the rug is 14.8 in, find the circumference of the rug. (This is the length of the material that she must use to bind the outer edge.)
Round your answer to the nearest tenth. Do not type the units in the space below.
recall that C = 2πr
To find the circumference of a circle, you can use the formula:
Circumference = 2 * pi * radius
In this case, the radius of the rug is given as 14.8 inches. The value of pi is approximately 3.14159.
Now, let's substitute the given values into the formula:
Circumference = 2 * 3.14159 * 14.8
Using a calculator, we can simplify this:
Circumference ≈ 2 * 3.14159 * 14.8 ≈ 92.768912
Round this answer to the nearest tenth:
Circumference ≈ 92.8
Therefore, the circumference of the rug, rounded to the nearest tenth, is 92.8 inches.
To find the circumference (C) of the circular rug, we can use the formula:
C = 2πr
Where r is the radius of the rug.
Given that the radius (r) is 14.8 in, we can substitute this value into the formula:
C = 2π(14.8)
Calculating this expression, we find:
C ≈ 2 * 3.14159 * 14.8 ≈ 92.79
Therefore, the circumference of the rug is approximately 92.8 (rounded to the nearest tenth).
