How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
How do i find circumference and area of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
What is the formula for the area of a circle with a diameter of 100?
The formula for the area of a circle is A = πr^2, where A is the area and r is the radius of the circle. To find the radius from the diameter, you divide the diameter by 2. So, for a circle with a diameter of 100, the radius would be 50. Plugging this into the formula, the area would be A = π(50)^2 = 2500π square units.
How do you find a area with the diameter of a circle?
Area = Pi(radius)squared. You only need the radius of a circle to find the area. To find the radius, when you have the diameter, divide the diameter by 2, because the diameter forms two radii. After you have found the radius, plug in the radius into the area equation: Area = Pi(radius)squared In other words, you can say the other equation for the area of a circle is: Area = Pi(1/2Diameter)squared
What is the diameter of a circle that is equal to pi?
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
How do you find the radius and diameter of the circle if you know the area?
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
What is the formula to find the area of a circle with the diameter in it?
Area = Pi(d/2)2 where d = diameter
How do you find the area of a circle using its diameter?
The area of a circle is pi(radius)2 Radius is half the diameter. Simply divide the diameter in half and enter it into the equation 3.14(diameter/2)2
How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
Equation to find the area of a circle?
Area of a circle = (pi) (R2)R = radius of the circle = 1/2 of its diameter
How do you find area if you know the diameter?
radius = diameter/2 area of a circle in square units = pi*radius2
How do you find the diameter when given the area?
depends greatly on the thing you are working with. assuming a circle with area A the diameter is 2*sqrt(A*pi) since A =r*r*pi and diameter=2*r
Find diameter when you only have area of a circle?
pi*radius2 = area of a circle radius2 = area/pi radius = square root of (area/pi) diameter = 2*radius
What is the approximate area of a circle with a diameter of 14 inches?
About 153.86 square in. To find out the area of a circle do: r^2*pi.
When radius is unknown then how to find area of a circle?
By dividing its diameter by 2 is equal to the radius of a circle and its area is pi*radius2
