How do you find the circumference of a circle if the diamter is 40cm?
circumference = pi*40cm
Find the ratio of the circumference to the diameter for each circle 3?
For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
How do you find the ratio of the circumference to the diameter?
You don't have to find it. It's always (pi) = 3.14159 (rounded) .
How do you find the ratio between two circles when the diameters are given?
If you mean ratio then I don't quite understand the question.. but if you mean RADIUS Then you take the diameter and divide it by two. ============================================== There's no such thing as the ratio of circles. You can find the ratio of their diameters, the ratio of their radiussesses, and the ratio of their areas. -- The ratio of their diameters is: One diameter divided by the other one. -- The ratio of their radiusses is the same number as the ratio of their diameters. -- The ratio of their areas is the square of that same number.
Two numbers are in the ratio 35 and their sum is 72 so what is the larger number?
to find the ratio divide the diameter by half.
If the diameter is 8 what is the circumference?
The ratio of a circle's circumference to its diameter is Pi, which is 3.14159. Hence, multiply the diameter by Pi to find a circle's circumference, or divide a circumference by Pi to find its diameter. 8 times pi = 25.13274123.
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
If you want to find the ratio of a circle how do you do it?
I think you mean "radius". It's half of the diameter.
How do you find the length of perimeter or circumference of a circle?
Since pi is the ratio of a circle's circumference to its diameter, multiply the diameter by pi (about 3.14159) to get the circumference.
The diameter of the moon is approximately one fourth of the diameter of the earth find the ratio of their surface areas?
Since the scale factor of the moon to the earth is 1:4, then the ratio of their areas will be the scale factor squared or 1:16. The ratio of their volumes will be the scale factor cubed or 1:64.
How do you use pi to find a circle?
pi is the ratio of a circle's diameter (the distance across it) to its circumference (the distance around it).
Find the area of a rectangle that is 20cm by 40cm?
It is 800 square cm
