The radius of a circle is the distance from the center of the circle to any point on its circumference. In this case, if the circle has a diameter of 20 feet, the radius would be half of that, which is 10 feet. So, the radius of a 20 ft circle is 10 feet.

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
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 area of a circle with 30 ft radius?
A circle with a radius of 30 feet has an area of 2,827.43 square feet.
What is the area of a circle with a radius of 4.3 ft?
A circle with a radius of 4.3 feet has an area of 58.09 square feet.
What is the radius of a 20cm circle?
That depends what you mean with "a 20 cm. circle". If 20 cm. is the radius, you already have the answer. If 20 cm. is the diameter, the radius is half the diameter. (10cm)
What is the diameter of a circle whose radius is 20 ft?
40 ft
What is the square foot of a circle that is 20 foot?
If the circle is 20 ft radius, the area is π·20² = 1256.637 ft² If the circle is 20 ft diameter, the area is π·(20/2)² = 314.1593 ft² If the circle is 20 ft circumference, the are is π·(20/2π)² = 63.66198 ft²
What is the radius of a 20 meter circle converted to feet?
32.8084 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 20 ft?
If the question refers to a square, then circumference = 4d, where d is the length of a side. 20 = 4d therefore d = 20/4 = 5 ft. If the question refers to a circle with a circumference (C) of 20', then C = 2πr, where r is the radius of the circle. 20 = 2πr therefore r = 20 ÷ 2π = 3.18 ft If the question refers to the circumference of a circle with radius 20', then C = 2π x 20 = 40π = 125.66 ft
What is the diameter of a circle with a radius of 21 ft?
If radius=21 ft, then diameter = 2*radius = 42 ft
How many ft in 22yd?
circle with radius with 22yd
How do you measure sq ft of a circle?
If you meant: How does one measure the area of a circle in Sqft, The formula is: Pi x Radius in Ft squared. i.e. Area of circle in SqFt. =(22/7) x Radius in Ft x Radius in Ft.
The circumference of a circle is 62.8 feet What is the radius of the circle in feet and find the area of the circle?
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
If the circumference of a circle is 2053 feet what is the radius of the circle?
Given the circumference of a circle the radius is: r = C / 2xPI So the radius of your circle is 326.7451 ft
What is the approximate area of a circle with a radius of 26 ft?
what is the approximate area of a circle with a radius of 26ft
If a circle with 10 ft diameter what is the radius?
Radius of circle: 10/2 = 5 feet
