Mean is 8
you have to add all the numbers and then divide it by the number of elements you have in this case 7
Answer:
Your Answer is C
Step-by-step explanation:
Volume of cylinder = πr²h = π x 4² x 6 = 96π
volume of cone = 1/3πR²H = 1/3π x 8² x 12 = 256π
You can see that volume of cone is more than twice of volume of cylinder. So she is not correct
Given:
The expression is
To find:
The error in Frankie's work.
Solution:
We need to simplify , so
and,
Now,
Therefore, there is error in Frankie's last step. In that step, he did not subtract the mixed fraction correctly.
11m
The area of a triangle is bh/2. If we know the height (8m), we can plug it into a=bh/2 for a=8h/2 or a=4h or a/4=h
Since we know the area (44m^2), we can put that in for 44/4=h or h=11 metres.
