It usually works well to do what the instructions tell you. Multiply each diameter by 3.14.
a) 3.14×6 cm = 18.84 cm
b) [can't read the picture]
d) 3.14×9 in = 28.26 in
e) 3.14×11 mm = 34.54 mm
Answer:

Hope this helped :) have a great rest of your day or evening!!!
Answer:
(D)9.5 Units
Step-by-step explanation:
We have two chords CD and AB intersecting at E.
Using the theorem of intersecting chords
AE X EB =CE X ED
AB=AE+EB
16=10+EB
EB=16-10=6
Therefore:
AE X EB =CE X ED
10 X 6 = 4 X ED
ED =60/4 =15
Therefore:
CD=CE+ED
=4+15
CD=19
Recall that CD is a diameter of the circle and;
Radius =Diameter/2
Therefore, radius of the circle =19/2 =9.5 Units
2. Addition and multiplication
Answer:
The answer is x < 8
Step-by-step explanation:
12x > 9(2x− 3) − 21
12x > 18x - 27 - 21
12x > 18x -48
12x - 18x > -48
-6x > -48
6x < 48
x < 48/6
x < 8
