What is the area of a circle with a circumference of 50pi?
The area of a circle is calculated using the formula A = πr^2. Given that the circumference of the circle is 50π, we can determine the radius using the formula C = 2πr, where C is the circumference. So, 50π = 2πr. Solving for r gives us the radius as 25. The area of the circle with radius 25 is then A = π(25)^2 = 625π.
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?
The formula for pi (π) is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. The formula for the area of a circle using pi is A = πr^2, where r is the radius of the circle.
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?
You can use the relationship between the circumference of the Earth and the circumference of the smaller latitude to calculate the Earth's circumference. Multiply the circumference of the smaller latitude by the cosine of the latitude. This will give you the circumference of a circle at that latitude, which can then be used to estimate the Earth's circumference.
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
