What is the combined area of the two bases of the following cylinder

Mathematics
1 answer:
Sauron [17]3 years ago

D. 226.08cm^2

Since we are finding the combined area of the two bases of the cylinder, we are adding the area of the first base with the second base. The formula for the base of a cylinder is pi x r^2, since it is a circle. Since the bases are the same, we can rewrite this as 2pi x r^2.

Since the diameter is 12cm and r = 1/2 diameter, r = 6cm.

Thus, A = 2(3.1415)(6)^2 = 226.08cm^2

(3, 1.5) (4,0) the slope
Naya [18.7K]

════════ ∘◦❁◦∘ ════════

<h3>Answer = -3/2</h3>

════════════════════

<h3>Known</h3>

x1 = 2

y1 = 1.5

x2 = 4

y2 = 0

════════════════════

<h3>Question</h3>

the slope = gradient (m)

════════════════════

<h3>Way to do </h3>

m =  \frac{y2 - y1}{x2 - x1}  =  \frac{(0 - 1.5)}{(4 - 2)}  =  \frac{( - 1.5)}{2}  = - \frac{3}{2}

════════════════════

<h3>Note</h3>

•Formula of the slope (m)

\boxed {\ m =  \frac{y2 - y1}{x2 - x1}}

How do you interpret the value of the mean or the median in a situation
natka813 [3]

Answer:

Adding all the numbers together and dividing by the number of numbers

Example:

1, 3, 5, 6, 6, 6, 8, 8, 35, 46

Adding them together results in 124

124 divded by the number of numbers is 124 / 10 = 12.4

So the mean / median in this example is 12.4

(I think, hopefully this helps and I hope you have a nice day!)

A 5K race is about 3.1 miles. Kevin runs 3.5 miles on Monday, 4 miles on Wednesday and 1.8 miles on Friday. About how many 5K ra
docker41 [41]

Answer:

<u>Kevin completed 3 races</u>

Step-by-step explanation:

So to solve this first you would add up all of the miles Kevin ran.

3.5+4+1.8=9.3

Then you would take the total amount he ran and divide it by 3.1 to see how many races he would have completed

9.3 / 3.1=3

A university's freshman class has 5000 students. 90% of those
exis [7]

Answer:

4,500

Step-by-step explanation:

To find the number of students majoring in economics, you must turn 90% into a decimal making it .9.

Then you multiply the decimal to how many students there are (5000x.9) and that gives you 4,500.
