Answer:

96π cm²

Step-by-step explanation:

Use the formula for the surface area of a cylinder:

A = 2πrh + 2πr²

Plug in the height and radius, and solve:

A = 2π(4)(8) + 2π(4)²

A = 2π(32) + 2π(16)

A = 64π + 32π

A = 96π

So, the surface area of the cylinder is 96π cm²

Find the total surface area of a cylinder with a height of 8 cm and radius of 4 cm. Leave your answer in terms of π.

According to the question, here we have to find out the T.S.A. or the total surface area of the cylinder using a certain formula then put the respective values and get the result in terms of π

T.S.A. of Cylinder = 2πr(h + r)

Here,

r represents radius

h represents height

Given Data :

Height = 8 cm

Radius = 4 cm

Using the formula we get

T.S.A. = 2π × 4 cm(8 cm + 4 cm)

T.S.A. = 8π cm(12 cm)

T.S.A. = 96π cm²

Henceforth, the required answer is 96π cm²

2ND OPTION IS CORRECT i.e. 96π cm²

How do I factor (x^2 + 1)^1/2 +2(x^2 + 1)^1/2

professor190 [17]

$(x^{2} + 1)^{ \frac{1}{2}} + 2((x^{2} + 1)^{ -\frac{1}{2}}) \\\\ Take \ out \ (x^{2} + 1)^{ \frac{1}{2}} \ like \ so: \\\\ (x^{2} + 1)^{ \frac{1}{2}}(1 + 2(x^{2} + 1)^{ -1}) \\\\ = (x^{2} + 1)^{ \frac{1}{2}}(1 + \frac{2}{(x^{2} \ + \ 1)}) \\\\ = (x^{2} + 1)^{ \frac{1}{2}}(\frac{2 \ + \ (x^{2} \ + \ 1)}{(x^{2} \ + \ 1)}) \\\\ = (x^{2} + 1)^{ \frac{1}{2}}(\frac{(x^{2} \ + \ 3)}{(x^{2} \ + \ 1)}) \\\\ = \frac{(x^{2} \ + \ 1)^{ \frac{1}{2}}(x^{2} \ + \ 3)}{(x^{2} \ + \ 1)} \\\\$
This is what I would think to do with such an expression;
It should be alright to leave it as it is on the last line as this should be its simplest form;
But, you could write it out as:
$\frac{(x^{2} \ + \ 3)}{(x^{2} \ + \ 1)^{ \frac{1}{2}}} \\\\
= \frac{(x^{2} \ + \ 3)}{ \sqrt{(x^{2} \ + \ 1)}}$

Beef hope me I need you to answer the question. What is n * 54 - 688-20 =???³

blsea [12.9K]

Answer:n= 1/3d - 2/3m

Step-by-step explanation:

d=2m+3n

Step 1: Flip the equation.

2m+3n=d

Step 2: Add -2m to both sides.

2m+3n+−2m=d+−2m

3n=d−2m

Step 3: Divide both sides by 3.

3n/3 = d-2m/3

Therefore

n= 1/3d - 2/3m

Hope this helps!

Plz name brainliest if possible.

Answer:

n = d - 2m

Step-by-step explanation:

First we want to get n alone on one side, so we should subtract 2m from both side;

d = 2m + 3n

3n = d - 2m

Now to get n by itself, we need to divide by 3 from both sides;

3n = d - 2m

n = d - 2m

*Pretend there is a fraction bar between d - 2m and 3
