Circunference=pi times diameter
diameter=16in
circunfernce=16pi in
that is exact because pi is irrational
if we were to aprox pi to 3.14 hen
16 times 3.14=50.24
so answer is 16pi or 50.24 in
Answer:
1. a = 5, b = 8
2. d = 2
Step-by-step explanation:
1. The sum of adjacent angle is 180 degree
115 + 8b +1 = 180
8b = 180 -116
b = 8
Similarly
14a - 5 + 115 = 180
14a = 180 -110
14a = 70
a = 14
2. Intersecting diagonals divide each other into equal halves
3d + 5 = 5d + 1
2d = 4
d = 2
Side BC is congruent to side DC. (That's what the hash marks mean.) Angle C is congruent with itself, and the right angles at B and D are all congruent.
Thus, you want to choose triangle names that show BC congruent to DC. The appropriate selection is the second one ...
∆ADC ≅ ∆EBC

Answer:
The answer should be y=2x-4.
Step-by-step explanation:
The slope of the line (rise/run) is 2/1, or 2, and the y-intercept is -4.
