What is the area of a circle with a circumference of 50pi?
To find the area of a circle, the formula is pi*r2, and the circumference is 2pi*r Now plug in the information given. Circumference is 50pi. 50pi = 2pi*r Divide both sides by pi. 50=2*r Divide both sides by 2. 25 = r The radius equals 25. Now to find the area, using pi*r2. We know the radius is 25. pi*(25)2 Find the square of 25. pi*625 The area of the circle is 625pi square units (about 1963.5 square units)
What do scientist measure distances around a circle?
Scientists measure distances around a circle using radians or degrees. Radians are the preferred unit because they provide a more direct relationship to the radius of the circle. One complete revolution around a circle is equivalent to 2π radians or 360 degrees.
What is the formula for pye?
What a useless site - I dont need the guesswork of someone who thinks they know what it is, I am looking for the proper answer and exactly how it is calculated. The site should be questions and not answers
How do you determine the circumference of the earth if you know a circumference of a smaller latitude and the number of degrees the latitude is from the equator?
Circumference of the earth at particular latitude can be determined using the formula, Circumference of the earth = 2*PI*r*cos(Φ0) where r = radius of the at particular latitude r = R * (1 - ((1 / 298.25722356) * (0.5 - 0.5 * COS (2 * Φ0)))) R= radius of the earth at equator Φ0= latitude
How do you determine the cubic inches of a ball if all you know is the circumference?
To determine the cubic inches of a ball when you only know the circumference, you first need to find the radius by dividing the circumference by 2π. Then, you can use the formula for the volume of a sphere, V = 4/3 πr³, where r is the radius that you calculated.
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 you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you fund the circumference of circle when you know the area?
You dived the area by the circumference of the circle.
When you know the circumference of a circle how do you find the diameter?
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
How do you find the area of a circle if the circumference is 10?
We know that the area of a circle is pi * r2. We also know that the circumference of a circle is pi * d. Therefore, when you know the circumference of a circle and want to know the area, divide the circumference by pi to give you the diameter of the circle, divide the diameter by 2 to give you the radius, square the radius and then multiply by pi to get the area. So, 10/pi = 3.183. 3.183/2 = 1.5915. 1.59152 = 2.533 2.533 * pi = 7.958 to 3 decimal places. The area of your circle is therefore 7.958cm2.
How do you find the circumference of a circle without knowing the area?
To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.
How do you find the perimeter if you already know the circumference of a circle?
The circumference of a circle is the length of the circle's perimeter.
How do you find the area of a circle when you already know the circumference?
radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi
How do you find the diameter of a circle if you know the circumference?
Divide the known circumference by pi to find the diameter of the circle.
How do you convert area of circle if you know the circumference?
It depends on what you want to convert the area of the circle into.
How do you find the circumference of a circle of you know the area?
Divide the area by pi, which gives you the square of the radius. Take the square root and multiply by 2 pi and you have the circumference.
How do you calculate the area of a circle if you know the circumference?
By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2
