A: 0.171 m, because 1 meter is 1,000 mm, and there is only 171 mm total.
Answer:
50.27 units
Step-by-step explanation:
The formula for the circumference of a circle is:
C = 
d
where, d = diameter
Now plug in the values as shown below:
C = 16
C = 50.27
Answer:
E is the same distance from A and B. ⇒ D
Step-by-step explanation:
<em>Let us explain the meaning of perpendicular bisector</em>
If line m is the perpendicular bisector of line n, then
- line m intersect line n at the mid-point of line n
- They form 4 right angles around this mid-point
∵ Line CD is the perpendicular bisector of segment AB
∴ Line CD intersects segment AB at the mid-point of AB
∵ Line CD and segment AB intersected at point E
→ That means E ∈ CD and E ∈ AB
∴ Point E is the mid-point of line AB
∴ Point E divides line AB into 2 equal parts
→ That means point E is at the same distance from points A and B
∴ E is the same distance from A and B.
Answer:
<h2>b. (0, 0) and (-3.5, 0)</h2>
Step-by-step explanation:
Look at the picture.
R=5
r(r-1)=30
r²+r=30
5²+5=30
5²=30-5
5²=25
5=5
Black box = r x 2
5 x 2 = 10
Black part of card is 10 sq cm.
