The volume of a cylinder is pi(r^2)h where r is the radius, and h is the height. In this case, the radius and height are the same. Therefore the volume is 3.14 times 8^3. This equals 1607.68.
1607.68 mm^3
Answer: Is there a total for how many kids like each? If there isn't than this is how I would solve it. For percentage purposes let's say there are 100 students. 50 like math, 50 like science. Half of the students who like math also like science, which means 75 percent of the school likes science. A third of students who like science also like math, and since 75 percent of the school of 100 children likes science, that would mean 1/3 of that is 25, which would mean 75 percentof all students like math. Hence the ratio, I believe, is 1 to 1.

Answer:
The first account will give more interest after one year.
Step-by-step explanation:
Blanche has to invest $8000 in a saving account.
(i) One account gives a 5.1% annual interest compounded annually.
So, after one year she will get an interest of dollars
(ii) In another account gives 3.1% annual interest compounded quarterly.
So, the quarterly interest is %.
Hence, after one year she will get an interest of dollars (Approximate)
Therefore, the first account will give more interest after one year.
Given
Your family has a circular swimming pool.
The radius of the pool is 9 feet and and its depth is 4 feet.
Find out the volume of the pool.
To proof
As depth is given in the question that means the shape of the swimming pool
is cylinder.
Formula
where r = radius
h = height
now
radius of the pool is 9 feet and and its depth is 4 feet.
put all the values in the above equation
we get
use 3.14 to approximate pi
we get
= 1017.4 ( approx )feet²
Hence proved
Answer:
The length of the side is 16 in. Therefore the perimeter is 100 in. The area is 368.
Step-by-step explanation:
For the area, separate into smaller shapes. Take the area of the two cubes, plus the area of the big rectangle.
So, 8x8=64
24x10=240
8x8=64
Add all those up and you get 368 and the area.
Hope this helps
