The volume of a can (right circular cylinder) is 10 cubic feet. the curved surface area is the area of the side. write the curve

The volume formula of a cylinder is given as:

V = π r^2 h

So plugging in the value of the volume:

10 ft^3 = π r^2 h

<span>h = 10 / (π r^2)  ---> eqtn 1</span>

 

The formula for the surface area of cylinder is:

s = 2 π r h + 2 π r^2

plugging in eqtn 1:

s = 2 π r [10 / (π r^2)] + 2 π r^2

<span>s = (20 / r) + 2 π r^2                         (ANSWER)</span>

Solve for a. Correct answer gets BRAINLIEST
Darina [25.2K]

Hey there!!

Equation given :

A = h ( a + b ) / 2

Multiply by 2 on both sides

2A = h ( a + b )

Divide by h on both sides

2A / h = a + b

Subtract by b on both sides

2A / h - ( b ) = a

Hence, the option ( a ) is the correct answer

Hope my answer helps!

What is the missing dimension of a rectangle or prism with the following dimensions and volume? Length 3 cm width 5 cm volume 45
olasank [31]
Hello! 

In order to find out the volume of any prism, you are to do length x width x height.

Because we only know the length and the width, we can multiply those to get started. 3 x 5 is 15, so we know that's what we can start with.

Because we know the volume, all we have to do is do h x 15 = volume (45). Now, what is height?

In order to find the height, we must find a number that, when multiplied by 15, equals 45. 

So we can try out 3, which when multiplied by 15, equals 45. 

That means 3 is your height.

Hope I helped! :)

In a group of 28 students, 12 study both Art and Biology.
MAVERICK [17]

Answer:

100%

Step-by-step explanation:

Use conditional probability:

P(B | A) = P(B and A) / P(A)

P(B | A) = (12/28) / P(A)

We need to find the probability that a student studies art.

P(A or B) = P(A) + P(B) − P(A and B)

24/28 = P(A) + (12+12)/28 − 12/28

P(A) = 12/28

P(B | A) = (12/28) / (12/28)

P(B | A) = 1

What this means is that all of the students who study art also study biology.

Lynn plotted point G, 3 units to the left and 2 units above point F. Where did lynn plot point G?
kvasek [131]

Answer:

G = (2,6)

Step-by-step explanation:

See Attachment for Complete Question

From the attachment, we can see that F is plotted at

F = (5,4)

On the x axis, G is 3 units to the left;

And on the y axis, G is 2 units above

So, the coordinates of G is calculated as:

G = (5-3,4+2)

G = (2,6)

Hence:

<em>G is plotted at (2,6)</em>
