The area of a circle if the diameter was s 7ft is 38.48ft

If the side of the square is s units then the diameter of the circle is s units and so its area is pi*s2/4 square units.

The formula for the area of a circle is πr2, or pi x radius^2 The radius of a circle is the diameter divided by two, and pi is approx. 3.1415926535

s diameter of the circle in the drawing above is the segment

Semicircle

The area of Circle S can be found by using the area formula for circles. The area of a circle is pi times the radius squared. So, the area of Circle S with a 1 inch radius is Pi inches squared.

If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.

The area of S is 16 square inches.

It means that somebody gives you a circle, and your job is to draw a square that hasthe same area as the circle you're given. In a shorthand manner of speaking, you tookthe circle and you "squared" it.In order to do it, you need to be able to measure lengths and draw right angles.-- Measure the diameter of the circle. The radius is 1/2 the diameter.Area of the circle = pi R2To draw the square, you need to know the right length 'S' for the side of the square.Since the area of the square is supposed to be the same as the area of the circle,S2 = pi R2S = R sqrt(pi) = 1/2 diameter sqrt(pi)S = (Diameter) x (1/2 sqrt(pi) )S = 0.88623 x DiameterConstruct a square with sides of that length, and you've "squared" the circle.

Four - Diameter is the length of the circle, one end to the other through the cirle, while radiusis from the middle of the circle , out. Hence Being half. s :)

The number four uniquely features in two circle equilibriums firstly by producing a numerically equal circumference and area when the diameter is four; and secondly by producing a numerically equal area and diameter when the circumference is four, as follows :When the DIAMETER of a circle measures 4 the CIRCUMFERENCE and AREA are both equal at:12.566370614359172When the CIRCUMFERENCE of a circle measures 4 the AREA and DIAMETER are both equal at:1.2732395447351627When the DIAMETER of a circle is greater than 4 the AREA is greater than the CIRCUMFERENCE.When the DIAMETER of a circle is less than 4 the AREA is less than the CIRCUMFERENCE.When the DIAMETER of a circle is 1 the CIRCUMFERENCE is Pi which equals:3.141592653589793238462643383279502884197169399 ...an so on to infinity.Multiplying the DIAMETER of a circle by Pi therefore determines its CIRCUMFERENCE.SQUARING the RADIUS of a circle and then multiplying it by Pi determines its AREA.If the DIAMETER of a circle is 4 then its RADIUS will be 2. When 2 is squared it becomes 4.Because both the DIAMETER and SQUARED RADIUS are 4 multiplying them by Pi brings both the CIRCUMFERENCE and AREA of the circle into EQUILIBRIUM.However, if the DIAMETER is increased TENFOLD the CIRCUMFERENCE also increases TENFOLD but the AREA increases ONE HUNDREDFOLD because the area always increases by the SQUARE OF THE MULTIPLIER (eg.Diameter x 100, Circumference x 100, Area x 10,000)When the CIRCUMFERENCE is 4 dividing it by Pi determines the DIAMETER which is in EQUILIBRIUM with the AREA, so dividing the AREA by Pi determines the SQUARE OF THE RADIUS which would make a good book title or movie.Anyway, you can play around with all this at the following link:http://www.math.com/students/calculators/s...rcle-solver.htmRevelation 7:1 "And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree."In the Bible the number FOUR appears 330 times in 289 verses.

the area s 45pie!
