Final answer:
To find the area of a segment of a circle without knowing the radius, you can use the formula: Area of the segment = (angle/360) x Area of the whole circle.
Step-by-step explanation:
To find the area of a segment of a circle without knowing the radius, you can use the following steps:
- Determine the angle of the segment. This can be given in the problem or measured if provided with a diagram.
- Find the area of the whole circle using the formula A = πr2.
- Calculate the fraction of the circle's area that the segment represents using the given angle.
- Multiply the fraction by the area of the whole circle to find the area of the segment.
For example, if the angle of the segment is 60 degrees and the area of the whole circle is 100 square units, the area of the segment would be (60/360) x 100 = 16.67 square units.
