What is the equation of the circle standard form?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
What is the formula for area for circle?
The formula for the area of a circle is πr2, written in verbal form as: "The value Pi times the radius of the circle squared", where r is the radius (half of the diameter, or the distance from the center to any point on the outer edge of the circle) of the circle, and π equals about 3.1415.
What is a circle in GEOMETRY?
It is a "circle". π=3.1415 (Pi) The radius of a circle = the distance form the center to the edge going in a straight line. The Diameter of a circle = radius x 2 The Area of a circle = radius2 x π The Circumference of a circle = diameter x π (or 2 × π × radius)
What is a radius circle?
If you mean "what is the radius of a circle", then the answer is the line segment or length from the center of circle to the set of points that form the circle. The radius is also half of the diameter.
What is the area of a circle with a radius of 6 inches?
Area = pi*62 = 113.0973355 or about 113.10 square inchesRemember that the area of a circle is (pi)r2, where r is the radius of the circle. You would plug the radius into the formula:(pi)r2(pi)(6)236 pi in2Or, if you want to put it into decimal form, 113.097 in2The area of a circle is given by (area) = (pi)*(radius)^2. So in this case, it would be:(pi)*(6 inches)^2 = 36(pi) square inches
What is the area of the circle?
A = Pi X R2, where Pi = the irrational form best known as 3.14 or 22/7, and R = the radius of the circle.
What is the radius to the nearest hundredth of circle whose area is 719 square feet in geometry form?
The radius, to the nearest hundreth, of a circle whose area is 719 square feet is 15.13.Another Answer:-When: pi*radius2 = 719 square feetThen: radius = square root of 719/pi => 15.13 feet rounded to the nearest 1/100
Can a chord be a radius?
Assuming that the question was meant to be about a chord (not chrod) and radius (not radious), the answer is no. A chord is a line joining two points on the circumference of a circle. One end of a radius is on the circumference but the other is at the centre.
How many cubic yards in a 25 ftcircle 2 in deep?
An area with these dimensions has a volume of 3.03 cubic yards.
Find the area of a circle that has a diameter of 4.2cm?
the formula for the area of a circle is A = pi * r^2 also, diameter = 2 * radius therefore, the radius must equal 2.1 therefore, A = 4.41*pi you can leave it in that form, but if you wanna evaluate and find a numerical value by using 3.14 instead of pi, you will get 13.8474
Can the radius of a circle be a decimal number?
Yes, the radius of a circle can be a decimal number. The radius is the distance from the center of the circle to any point on its circumference, and this distance can be measured in decimal form. In fact, many real-world measurements result in decimal values for the radius of a circle.
A chord of a circle is 9 inches long and its midpoint is 6inches from the center of the circle What is the radius of the circle?
Half of the chord, the distance of the midpoint from the center, and a radius, form a right triangle, with the radius as its hypotenuse. (4.5)2 + (6)2 = (radius)2 (20.25) + (36) = 56.25 = R2 Radius = 7.5 inches
