Answer: A) 46.5 cm
Step-by-step explanation:
Circumference = 2 π r or Circumference = π d
In this case, they give us the diameter = 14.8 cm. Therefore the radius = 14.8/2 = 7.4 cm.
π ≈ 3.14.
We can use either equation above, but because the diameter was given, we will use c = πd for simplicity.
C = π d
= (3.14)(14.8)
= 46.47 cm, which rounds to 46.5 cm
Answer:
1. Not True
2. Not True
3. Not True
4. Not True
5. True
Step-by-step explanation:
As given,
1.
2 + 3 = 9
⇒ 5 = 9
Not True
2.
4 > 5 + 7
⇒4 > 12
Not True
3.
9 = 12 + 2
⇒9 = 14
Not True
4.
2 - 3 ≥ 2
-1 ≥ 2
Not True
5.
61 ≠ 5 - 12
⇒61 ≠ -7
True
Answer:
1/6 of a yard
Step-by-step explanation:
Length of the board = 5/6 yard
He needs to cut the board into 5 equal sections.
Length of each section = length of the board ÷ number of sections
= 5/6 ÷ 5
= 5/6 × 1/5
= (5*1)/(6*5)
= 5/30
= 1/6
Length of each section = 1/6 of a yard
