∙ 10y agoRadius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
The formula for finding the Area is A = Pi x R-squared, where Pi is 3.1416 and R-squared is the radius multiplied by itself: A = 3.1416 x (5 x 5)= 3.1416 x 25 = 78.54 sq ft. The formula for finding the circumference is C = Pi x D where Pi is 3.1416 and D is the diameter (diameter is Radius x 2): C = 3.1416 x 10 = 31.416 ft.

Assuming the shape is a triangle, the area is 11.40 sq ft, approx.
It is not possible to determine the area of a quadrilateral given only the length of its four sides.
Area of the circle = pi*2.52 = 19.635 square feet rounded to 3 decimal places
The circumference is about 15.7 feet.
pi * 5 = 15.7079633 Circumference = pi * Diameter
78.5 ft2(3.14)(5ft)2
5ft * Pi = Approximately 15.7ft
Area = 25*pi square feet

the formula to start off with is the circumference is pi x diameter therefore re-arranging the formula the diameter is the circumference divided by pi diameter = circumference / pi = 18ft 8in / 3.1415 = 5ft and 11 inches to the nearest inch (to be more precice to diameter is 5ft 11.3 inches--- note it is more difficult to work in feet and inches and easier to work in metres and centimetres)
If the width is 5ft and the length is 5ft then the area is 25ft. You just need to multiply the length by the width.
The radius is half of the diameter so it is 2.5 Feet.
Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
A circle with a radius of 5 feet has a circumference of 31.4 feet.
