Read each question carefully and calculate the area of the segment of the circle. Show all your work and round your answers to two decimal places where necessary.
1. A circle has a radius of 10 cm. Find the area of the segment formed by a central angle of 60 degrees. (Use π = 3.14 and √3 = 1.73)
2. Calculate the area of the segment of a circle with a radius of 12 inches and a central angle of 90 degrees. (Use π = 3.14)
3. The formula for the area of a sector of a circle is A = (θ/360) * πr², where θ is the central angle in degrees and r is the .
4. To find the area of a segment, you subtract the area of the from the area of the sector.
5. A segment of a circle is the region bounded by an arc and two radii.
True
False
6. The area of a triangle formed by two radii and a chord can be calculated using 0.5 * r² * sin(θ).
True
False
7. A circular garden has a radius of 15 meters. A path is built along a chord that subtends a central angle of 120 degrees. What is the area of the smaller segment of the garden? (Use π = 3.14 and √3 = 1.73)
