How do you find the circumfrence of a circle if you have the radius?
the circumfrence of a circle is pi times it's radius squared.
What is the distance around circle with 72 ft radius?
Diameter = 2 x (radius)Circumference = (pi) x (diameter) = (pi) x (2 x 72) = 144 pi = 452.39-ft (rounded)
What is the radius of a 20 ft circle?
Here, 20 ft is the cicumference of the circle.Clearly, 2*Î?*r = 20 ft, where r is the radius of the circle.i.e. 2*3.14*r = 20 ft6.14*r = 20 ftr = 3.311 ft
What would the perimeter of a 20ft semicircle be?
That depends on what you mean by a "20 ft semicircle".A semi-circle is a half circle.A 20 ft circle could be:A circle of diameter 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2π 20 ft + 20 ft= 10π + 20 ft≈ 51.42 ftA circle of radius 20 ftThe perimeter of the semicircle is half the circumference plus double the radius → perimeter = 1/2 2π 20 ft + 2 x 20 ft= 20π + 40 ft≈ 102.08 ftA circle of circumference 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2 20 ft + 20 ft ÷ π= 10 ft + 20/π ft≈ 16.37 ftHowever, if a 20 ft circle is a circle with a circumference (= perimeter) of 20 ft then a 20 ft semi-circle could be a semicircle with a perimeter of 20 ft→ perimeter = 20 ft
What is the circumference of an 8 ft circle?
The circumference of an 8 ft circle is: 25.1 feet.
What is the circumference of a circle when the radius is 25 ft?
The circumference of a circle when the radius is 25 feet equals about 157.08 feet.
What is the radius of a ft circumference?
Radius of a circle = circumference/2*pi
What is the circumference when the radius is 25 FT?
157 ft
What is the circumference of a circle with a radius of 25 feet?
The circumference is 50π ft or 157.08 ft.
What is the circumference of 18 ft radius?
The circumference of a circle is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For an 18-foot radius, the circumference would be ( C = 2\pi(18) ), which equals ( 36\pi ) feet. Approximating (\pi) as 3.14, the circumference is about 113.1 feet.
What is the circumference of a circle witha radius of 4 ft?
The circumference of a circle with a radius of 4 ft is: 25.13 feet (r x 2 x Pi = circumference).
What is the circumference of a circle of radius 1.5 ft?
Circumference of a circle = 2*pi*radius or diameter*pi so in this case circumference = 2 x 3.142 x 1.5 ft = 9.42 ft
What is the circumference of a circle that has a radius of 12 ft?
The circumference of a circle that has a radius of 12 feet is about 75.4 feet.
What is the circumference of a circle with radius of 5.5 ft?
A circle with a radius of 5.5 feet has a circumference of 34.56 feet.
What is the circumference of a circle with radius 14 ft?
A circle with a radius of 14 feet has a circumference of 87.96 feet.
What is the circumference of 6.5 ft radius?
20,410ft
What is the circumference if the radius is 1 ft?
about 6.28
