Answer:
97.7 cm
Step-by-step explanation:
The volume of a cylinder is given by the equation
where:
r is the radius of the cylinder
h is the height of the cylinder
V is the volume
In this problem, we know that the volume of the cylinder is
Here we are not given the height; here, let's assume it is
h = 20 cm
Therefore, we can re-arrange the equation to find the missing dimension, which is the radius of the cylinder:
n = 4 means that you are going to divide the area in 4 equal parts, that means that the size of the intervals is [20-4] / 4 = 16 / 4 = 4.
Now you can estimate the area from 4 to 20, by adding the area from 4 to 8 + the area from 8 to 12 + the area from 12 to 16 + the area from 16 to 20
And estimate each small area by a rectangle or a trapezoid.
As a trapezoid, area of each region is [f(x) + f(x+4)] /2 [x +4 - x] = [f(x) + f(x+4)] /2 [4] =
=[f(x) + f(x+4)] / 8
Area from 4 to 8: [11 +25] / 8 = 4.50
Area from 8 to 12: [25+16]/8 = 5.125
Area from 12 to 16 = [16+9]/8 = 3.125
Area from 16 to 20 = [9+31]/8 = 5.00
Total area = 17.75
Answer: 17.75
To answer this question, you must first understand what a fourth is. 1/4 is simply when a one is split into four parts, and you take one of those parts. Imagine you have a pie, and you cut it into four equal pieces. If you take one of those four pieces, you have one fourth of the pie. So if you have three fourths of the pie, you have three pieces out of the four total. This question is basically asking: "If you have three pieces out of four, how many pieces do you need to make one whole pie?"
Therefore, the problem looks like this:
3/4 + ?/4 = 1
and therefore the answer is 1/4 because you only need one fourth to make a whole number.
