c = circumference
pi = 3.14
r = radius = 9 inches
d = diameter
c=pi*d
The radius is half of the diameter, d = 2r. Then d = 2*9=18.
plug into equation. c= pi*d = 3.14*18
round accordingly and you may want to include that the measurement you end up with is in inches.
Answer:
⟨-5, -1⟩
Step-by-step explanation:
Vector:
A vector is given by its endpoint subtracted by its initial point.
Vector u has initial point at (3, 9) and terminal point at (–7, 5)
Then

Vector v has initial point at (1, –4) and terminal point at (6, –1).
Then

What is u + v in component form?

⟨-5, -1⟩ is the answer.
Answer:
4 + 12 × 19 + 24
Step-by-step explanation:
Hullo!
Words like "added or sum", represent addition.
Words like "times", represent multiplication.
Words like "subtracted or took away", represent subtraction.
Words like "divided or split up", represent division.
Therefore, we can express the equation 4 added to 12 times 19 plus 24 can be rewritten as
in expression format.
