Answer: V = 256
Step-by-step explanation:
Since the radius and the height are given , we just need to substitute the values into the formula for calculating the volume of a cylinder , which is given by:
V = h
r = 8
h =4
so ,
V = ××4
V = ×8×8×4
V = ×64×4
V = ×256
Therefore :
V = 256
Answer:
12 adults
Step-by-step explanation:
We can solve this in a couple of simple steps. First, since there are 3 adults for every 8 students we add these two numbers together
3+8 = 11
Now we simply divide this number by the total amount of people that went to the trip in order to get how many times this set of adults and students repeats itself.
44 / 11 = 4
Finally, we multiply this number by the set of 3 adults in order to find out how many adults went to the trip.
4 * 3 = 12 adults
8 * 3 = 32 Students
Given:
The vertices of the rectangle ABCD are A(0,1), B(2,4), C(6,0), D(4,-3).
To find:
The area of the rectangle.
Solution:
Distance formula:
Using the distance formula, we get
Similarly,
Now, the length of the rectangle is and the width of the rectangle is . So, the area of the rectangle is:
Therefore, the area of the rectangle is 20 square units.
