Answer:
3pi or approximately 9.42
Step-by-step explanation:
The diameter is 3
The circumference is given by
C = pi *d
C =3 pi
We can approximate pi by 3.14
C = 3*3.14
C =9.42
Answer:
-120 degrees.
Step-by-step explanation:
This triangle has a rotational symmetry of 3 (it repeats its orientation 3 times as it makes a complete circle around the center), so the angle of rotation is 360 / 3 = 120 degrees.
As the rotation is counter clockwise strictly speaking the answer is -120 degrees.
1-r=-5
add r to both sides so the one side cancels out, then it should be 1=r-5
then you add -5 on each sides (because what you do to one side you must do to the other) and it would then have r on its own side which would give you your answer of r=6. To check 1-6 does equal -5
Answer:
60 inches
Step-by-step explanation:
Fill in the given numbers and solve for length. Then convert to inches.
18 ft = 2L +2(4 ft)
10 ft = 2L . . . . . . . . subtract 8 ft
5 ft = L = 5×(12 in) = 60 in
The length of Sarah's back yard is 60 inches.
