Answer:
The radius of the tree trunk is 7 inches.
Step-by-step explanation:
circumference = 2(3.14)radius
43.96 = 2(3.14) r
43.96 = 6.28r
7 = r
Answer:
-6 + 12x
Explanation:
Good luck. Have a great day.
Since the figure is a parallelogram, then SP=RQ, and SR=PQ.
To find SR, we draw right triangle SAR, as shown in the picture, where the coordinates of A are clearly (-3, -2).
Thus, we can see that SA=4 units, and AR=4 units. By the Pythagorean theorem,
Similarly, to find SP, which is equal to QR, we draw the triangle PBS, where the coordinates of B are (-2, 2).
Clearly, PB=3 and SB=1, thus using the Pythagorean theorem in right triangle PBS:
units.
The perimeter of the parallelogram is SP+RQ+SR+PQ=
.
