Answer:8 π inches
Step-by-step explanation:The formula for circumference is diameter *
π
The radius of a circle is always exactly half of the circles diameter.
Therefore, the diameter will be 8 inches
Multiply the diameter, 8 by π
to determine the circumference.
Answer:
Last Graph (4th one)
Step-by-step explanation:
The equation given is
Since we want increase of 25%, the value of b would be 1.25, so we have:
The graph should be increasing so we can immediately eliminate 2nd and 3rd graphs since they are clearly decreasing. We now have to choose between 1st graph and 4th graph.
<u>1st graph:</u>
Let's take the point (-20,30)
<u>2nd graph:</u>
Let's take the point (-20,4.5)
hence, this makes sense. So the correct graph is 4th one.
Answer:
2/3
Step-by-step explanation:
Total number of marbles = 3 + 4 + 5 = 12
Pr (red marble) 3/12
Pr (Blue marble) = 4/12
Pr (white marble) = 5/12
Probability of drawing either a red or a white marble
= Pr ( red) + Pr (white)
= 3/12 + 5/12
= 8/12
= 2/3
They all have 3 angles and 3 sides
