Who were the first group of people known to calculate the area of a circle using a pi approximation of 3?
It is not known. The Rhind Papyrus describes how the area of a circle is related to pi where pi was estimated as (4/3)4 ≈ 3.1605 (approx).
The Rhind Papyrus dates from around 1700 BCE. So either very ancient people used pi = 3 or else they were later people who were dogmatically required to use pi = 3.

What is the best approximation for the circle with a diameter of 13 meters Use 3.14 to approximate pi.?
To find the best approximation for the circle with a diameter of 13 meters, we first calculate its radius, which is half the diameter, giving us a radius of 6.5 meters. The circumference of the circle can be calculated using the formula (C = \pi \times d), where (d) is the diameter. Using 3.14 for (\pi), the circumference is (C = 3.14 \times 13 \approx 40.82) meters. The area can be calculated using the formula (A = \pi \times r^2), resulting in (A \approx 3.14 \times (6.5)^2 \approx 132.65) square meters.
How do you calculate the diameter of a circle if you know the area?
First, divide your answer by 2 Next, divide that answer by 3.14 Then, multiply that answer by 2 there's your answer
How do you calculate the square footage of a half circle 2 thick?
To calculate the square footage of a half circle, you first need to determine the area of a full circle using the formula ( A = \pi r^2 ), where ( r ) is the radius. Since you're interested in a half circle, you would divide the area by 2: ( \text{Area of half circle} = \frac{1}{2} \pi r^2 ). If the thickness (2 units) pertains to a border or a layer around the half circle, you would need to calculate the area of the larger half circle (with radius ( r + 2 )) and subtract the area of the smaller half circle (with radius ( r )).
What is the square foot area of a circle 128 foot cercumference?
A circle of radius r has a circumference of 2*Pi*r and an area of Pi*r*r, where Pi is the constant which is approximately 3.14159. Use the first equation to calculate the radius and then the second to calculate the area.
How did Archimedes calculate pi?
He calculated the perimeters of regular polygons inscribed within a unit circle and circumscribing the circle (outside the circle). The first is always less than the circumference of the circle ( = 2*pi) and the second is always more. As you increase the number of sides of the polygons, the polygons get closer and closer to the circle and their perimeters get nearer to the circumference.
How do you calculate your menstrual circle days?
It's not a menstrual "circle" - it's a menstrual cycle. And on another note, you can calculate the menstrual days by marking it down on your calander; from the first day you started.

Where can you apply binomial expansion in engineering?
To calculate an approximate value for, say 99.55, you could first rewrite it as 1005*(1-0.005)5 and then use the binomial expansion of the first three terms of (1-0.005)5 to get a pretty good approximation - accurate to 1.2 parts in a million! You can calculate the first three terms without a computer if you know your basic times tables.
How much dirt do I need to buy to fill a fourteen foot circle?
To calculate the volume of dirt needed to fill a circular area, you first need to find the area of the circle (πr^2, where r is the radius). In this case, for a 14-foot circle, the radius is 7 feet. Once you find the area, you can calculate the volume of dirt needed based on the desired depth of filling the circle.
