How do you find the area of a circle only knowing the radius?
If you know the radius (say it's 4), square the radius and multiply that number by pi. So for a radius of four, it would be 4 X 4 = 16 X 3.14 = 50.24, the area of the circle.
How do you find the area of a circle knowing only the circumference?
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
How do you find the radius of a cone knowing only side length?
You cannot.
How do you find radius if cone knowing only the height?
You must have another parameter
How do you find the radius of a circle when given only the area?
Area = pi*radius2 So, radius = sqrt(area/pi)
How do you find the area of a circle by only knowing the radius?
Since the area of a circle is pi times radius squared, take the radius and square it. Then, multiply that by 3.14, or pi to get the area of the circle.
How do you find a sphere surface area where the radius equals 26cm?
The surface area of every sphere is (4 pi) times (the radius squared).Knowing that, you can find the surface area of not only the one you'reasking about right now, but of every sphere that ever was, is, or will be !
How do you find the area of a circle only knowing the radius?
If you know the radius (say it's 4), square the radius and multiply that number by pi. So for a radius of four, it would be 4 X 4 = 16 X 3.14 = 50.24, the area of the circle.
How do you find the radius of an object by only knowing it's circumference?
Radius = Circumference/(2*pi)
How do you find the radius of a cone knowing only side length?
You cannot.
How do you find the area of a circle knowing only the circumference?
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
How do you find the radius of a circle if you only know the area?
Radius = +sqrt(Area/pi)
How do you find radius if cone knowing only the height?
You must have another parameter
How do you find the radius of a cone knowing only the diameter?
The radius is half the diameter, so just divide the diameter by 2.
How do you find the radius of a circle when given only the area?
Area = pi*radius2 So, radius = sqrt(area/pi)
If the area of the square is 722in find the radius?
A square doesent have a radius only circles do. :)
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.
