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 a circle whose diameter is 20 cm?
The formula to calculate the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter is 20 cm, the radius would be half of that, which is 10 cm. Plugging in the radius into the formula, we get A = π(10)^2 = 100π cm^2. Therefore, the area of the circle with a diameter of 20 cm is 100π square centimeters.
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
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
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.
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'
If the radius of a circle is 10 inches what is the diameter?
The radius is half the diameter. The diameter is twice the radius. If the radius is 10 inches, the diameter is twice that, or 20 inches. The radius is any straight line that connects a point on the circle with it's center. The diameter is a line segment that connects two points on a cirle throught the center of the circle.Answer:Let r be the radius of the circle and d be the diameter of the circle. We know that the diameter = 2 * radius of the circle. Given the radius r = 10 inches. Diameter d = 2 * 10 Diameter = 20 inches.
