Area of a circle is pi x r^2
R = d/2 = 14.2 = 7
Area = 3.14 x 7^2
Area = 3.14 x 49
Area = 153.86 round to 154
Answer is 154 square feet.
Answer:
28 beads were used to make the bracelet. 7 beads were not yellow.
Step-by-step explanation:
3/4 beads used to make the bracelet are yellow
If 21 beads are 3/4 of the bracelet and yellow
1/3 of the 21 beads would be 1/4 of the bracelet
7 beads are 1/3 of 21 beads
7 × 4 = 28 beads

For lines to be parallel, the slopes have to be the SAME.
For lines to be perpendicular, the slopes have to be the exact opposite. (opposite sign and number)
For example(perpendicular):
slope is 2
the perpendicular slope is -1/2
slope is -4/5
the perpendicular slope is 5/4
12. line a and b are perpendicular
13. Line a: y = 3/5x + 1
Line b: y = 3/5x - 2/5
Line c: y = 4/6 + 5/3x
line a and b are parallel
14. Line a: y = 3x + 6
Line b: y = 6 - 3x
Line c: y = 2/3x + 6
Neither, none of them are parallel or perpendicular
15. Line a: y = -2/3 + 4/3x
Line b: y = -1/4 - 3/4x
Line c: y = 5 + 3/4x
line a and b are perpendicular
