What is the radius of a circle with a circumference of 20 inches?
r = 3.18 inches.
What is the area of a circle with a diameter of 20 cm?
A circle with a radius of 10 cm has an area of 314.16 square cm
Area of an arch of circle with a radius of 70 feet The angle of the arch is 20 degrees?
855.21 square feet. A circle with a radius 70 would be (pi)(radius squared) = (3.1416) (70) (70) = 15,393.8 square feet. With a 20 degree angle that is 20/360ths of a circle, so multiply your circle area by 20 and divide by 360 = 855.21 square feet.
If a circles radius is 20 inches what is the circumference?
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
What is the area of 20 inch diameter circle?
Area of circle: pi*10^2 = 100*pi square inches
Find the area of a circle if the radius is 20 in?
1256 inches squared
What is the area of a circle that has a radius of 20 inches?
400 pi = 1,256.64 square inches (rounded)
How do you find the radius of a circle with a circumference of 20 inches?
radius = 20/(2*pi) = 3.183098862 inches
What is the area of a circle with radius of 20 yards?
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
How many square inches in a 40 inch diameter circle?
Area of a circle = πr² (remember that r or radius is exactly half of the diameter) Radius therefore = 40/2 = 20 inches Thus the Area = 3.14159 × 20 squared = 1256.636 square inches
Area of circle with 20 inch radius?
Area = pi*r2 So r = 20 inch gives area = 1256.64 sq inches.
What is the radius of a circle with a circumference of 20 inches?
r = 3.18 inches.
What is the area of a circle with a radius of 20yd?
A circle with a radius of 20 yards has an area of 1,256.64 square yards.
If the area of a circle is 20 square inches what is the diameter?
If the area of a circle is 20 square inches the diameter is: 5.046 inches.
How many square inches in a 20 inch Dia. circle?
15.707963267948965 square inches. I think.* * * * *That is a very accurate but very wrong answer.The correct answer is 314.159 sq inches (to 3 dp).******Yes, the correct answer is 314.159. Here's why:The area of a circle can be found by multiplying pi (3.14159...) by the square of the radius. (The radius of a circle is 1/2 the diameter)This 20" circle has a radius of 10", so its area is 3.14*10"*10"=314.159
Diameter of circle in inches if the radius is 20 feet.?
40'
What is the area of a circle you can surround with 20 feet of fence?
Radius of a circle with 20' circumference = 20'/2pi = 3.18'Area of a circle with 3.18' radius = ((3.18')^2)pi = 31.8 square feet
