Answer :
The correct answer is a) 25.1 feet.
To determine the amount of ribbon Martha needs, we must calculate the circumference of the tablecloth. The circumference [tex]\( C \)[/tex] of a circle can be found using the formula [tex]\( C = \pi d \)[/tex], where [tex]d[/tex] is the diameter of the circle and [tex]\( \pi \) (pi)[/tex] is approximately 3.14.
Given that the diameter [tex]\( d \)[/tex]of the tablecloth is 8 feet, we can plug this value into the formula:
[tex]\[ C = \pi d = 3.14 \times 8 \text{ feet} \][/tex]
Now, we perform the multiplication:
[tex]\[ C = 3.14 \times 8 = 25.12 \text{ feet} \][/tex]
Since we are looking for an approximate value, we can round this to the nearest tenth:
[tex]\[ C \approx 25.1 \text{ feet} \][/tex]
Therefore, Martha will need approximately 25.1 feet of ribbon to go around the edge of the tablecloth."
Answer:
a) 25.1 feet to the nearest tenth.
Step-by-step explanation:
Circumference of a circle = pi * diameter.
So, she needs 8 * 3.14
= 25,12 ft
