Answer:
If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²
Then you do r * π *r which would be 78.5. so C is your answer.
Step-by-step explanation:
Answer: 12,8 approximately 13 cones
Step-by-step explanation:
1] volume of a cone
V=1/3πr^2h
V=1/3π(3)^2(5)
V=47,12 cubic inches
2] volume of a cylinder
V=πr^2h
V=π(8)^2(3)
V=603.19
Now devide the volume of a cylinder by the volume of a cone
603,19÷47,12=12,8 cones
If there are ten black pens, eight blue pens, and twenty pens in total, then there are 2 red pens. This means that the ratio of red to black is 2:10=1:5. Hope this helps!

Answer:
2
Step-by-step explanation:
In function notation, f(x) equals the y value and the x equals the x value. So this question is asking you to find the value of y when x=-2. To do this find -2 on the graph and find the point with the same x value, then find what value of y it is on. In this case, f(-2)=2.
