Jessica has a circular birdbath in her backyard with a radius of 1.25 feet. She wants to place a decorative border around the circumference of the birdbath. If the border costs $3.60 per foot, how much will the border for the birdbath cost Jessica in all? Use 3.14 for pi.
impatient much?
see your previous post.
$14.13
To find the cost of the border for the birdbath, we need to calculate the circumference of the birdbath first.
The formula to calculate the circumference of a circle is C = 2πr, where C represents the circumference and r represents the radius.
Given that the radius of the birdbath is 1.25 feet, we can plug in the values into the formula:
C = 2 * 3.14 * 1.25
Calculating this, we get:
C = 7.85 feet
The circumference of the birdbath is 7.85 feet.
Now, we need to find the cost of the decorative border. Given that the border costs $3.60 per foot, we can multiply the cost per foot by the circumference of the birdbath:
Cost = $3.60 * 7.85
Calculating this, we get:
Cost = $28.26
Therefore, the border for the birdbath will cost Jessica a total of $28.26.
