Radius of circle: 157/2pi = 25 m rounded

The distance around any object is called its perimeter. The perimeter of a circle has a specific formula: 2(pi)r where pi is a number that is approximately 3.14 and r represents the circle's radius. In this case we are given the circle's diameter, however remember that the diameter of a circle equals two times its radius. So if: d = 50' and d = 2r Then r = 25' Now plus this radius into or equation to get: 2(3.14)(25) = 157' To get the distance around this circle 8 times, multiply the perimeter by 8: 157' * 8 = 1,256 feet

1 acre = 43560 sq ft→ 0.18 acre = 0.18 x 43560 sq ft= 7840.8 sq ft.There is no definite answer for the length and width of a building lot as the building lot can have any length and width as long asits area(length x width) is 7840.8 sq ft.If it is a square building lot, it would be approx 88.55 ft by 88.55 ft.However, if it is rectangular, it could be approx 98 ft by 80 ft, or 131 ft by 60 ft, or 196 ft by 40 ft, or 157 ft by 50 ft, or even 7480 ft by 1 ft!

I am delighted to say that there are actually nine ways! 12 x 483 = 5796 42 x 138 = 5796 18 x 297 = 5346 27 x 198 = 5346 28 x 157 = 4396 39 x 186 = 7254 48 x 159 = 7632 4 x 1738 = 6952 4 x 1963 = 7852 I wrote some javascript (don't know any other programming codes!) to come up with the first seven. It was little more than a search through the various permutations, with only a few shortcuts. (It would be interesting if anybody could think of a neater way of finding the solutions.) I overlooked the last two - Henry Ernest Duden takes sole credit for them. The list is exhaustive - there are no other solutions.

Radius of circle: 157/2pi = 25 m rounded

Circumference of a circle = 2*pi*radius Circumference = 2*pi*25 =157.0796327 inches or 157 inches correct to three significant figures.

If the diameter is 50 inch, then the area circumference would be about 157. C=d(pi) 50*3.14=157

Taking pi as 3.14:- Radius: 27.6/(2*3.14) = 690/157 cm Area of circle: 3.14*(690/157) squared = 60.65 square cm rounded to 2 decimal places

157 inches.

157 ft

Circle circumference = 2 pi d = 2 (3.14 ) 25 = 157

Circumference = 2*pi*r Circumference = 2*3.14*25 => 157 inches

Diameter: 157/3.14 = 50 meters

THE FORMULA FOR FINDING THE CIRCUMFERENCE IS:CIRCUMFERENCE EQUALS DIAMETER TIMES 3.14In basic words:What do you know?You know you need to find the circumference of the circle, which is the distance all the way around the circle.You know the radius is 25 inches, the radius is the measurement from the center to the circumference of the circle.You know the formula needs the diameter, a diameter being the length of a line connecting two points on the circumference, touching the center of the circle, maintaining a straight line.With all this information, you can figure out that the radius is half the diameter.Now, begin your math.Problem: What is the circumference of a circle when you know the radius is 25 inches?Formula: Circumference= Diameter X 3.14 which is known as pi.Radius Diameter CircumferenceR=25 D=R times 2Replace variable R with the correct number:2525 multiplied by 2 is 50 which means that D=5050 multiplied by 3.14 is 157The circumference is 157

625*pi, or approximately 1,963 square feet This is the answer for square feet or area of the circle. pi*radius squared . The linear feet or circumference is found by multiplying the diameter times pi. answer is 50*pi or about 157 feet rounding pi to 3.14

C = pi * d C = 3.14 * 50 C = 157
