Answer:
B
Step-by-step explanation:
We know that:
-measuring a cone
-diameter: 18 units
-height: 8 units
We need to know how to find the volume of this cone. To do this, we need the equation to find the volume of a cone:
where r=radius and h=height
Upon assessing this equation we also now know that we are missing a radius.
For a circle, the radius is the distance from the midpoint, center, to the border of the circle. The diameter is the distance from the border of one circle to another, passing through the midpoint. Knowing this, we can conclude that the diameter is two times the radius.
Using this information we can figure out the radius for this cone: 9 units.
Now that we have the radius, we can plug in the rest of the numbers with the correct placements.
square the 9 by calculating 9 times 9.
combine like terms and keep pi separate.
V=216 cubic units
Since this problem is asking for volume, we will used cubic units.
Answer:
12.34
Step-by-step explanation:
For divide by the number then you get the answer
I want to say it is savings but I can be wrong. But I believe it is savings.
The answer is A
the answer is A
700
what i did was i divided 7000 by 10 and i got 700. then to check, i multiplied 700 by 10 and got 7000
First, we need to convert all the fractions to have the same denominator. 10 and 25 are both multiples of 100, so 100 would be appropriate.
Sam has a 7/25 chance. Because we want ?/100, something needs to change. To get from 25 to 100, you need to times 25 by 4, right? So, do the same with the 7.
7 x 4 = 28. Therefore Sam has a 28/100 chance.
Sue has 3/10. Using the same method, we can see that 3 needs to be multiplied by 10 (because 10 times 10 = 100). So Sue has a 30/100 chance.
Tom is already in the fraction we like, so just keep this as 21/100.
Now, add 28/100, 30/100 and 21/100 to get 79/100.
Because won of them will get the role of class president, we know that the probability adds to 1. To get a full probability (100/100, or 1), what needs to be added to 79/100?
Another way of going about this is 100/100-79/100. The answer is 21/100
The probability of Liz winning is 21/100.
Let me know if this is still unclear, I would be more than happy to explain in more detail if necessary :)
