What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
If the diameter of a circle is 36 what is the radius?
The radius of a circle is always half of the diameter. Therefore, if the diameter of a circle is 36 units, the radius would be half of 36, which is 18 units. The formula for finding the radius from the diameter is radius = diameter / 2. So, in this case, the radius would be 18 units.
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
Formula for finding the circumference of cone?
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
What is the diameter of a circle with a circumference of 49 centimeters?
Oh, dude, math time! So, the formula for finding the diameter of a circle from the circumference is dividing the circumference by π (pi). In this case, 49 divided by π is approximately 15.57 centimeters. So, the diameter of the circle is around 15.57 centimeters. Easy peasy, right?
