What is the volume of a cylinder with base radius 2 and height 5?

Mathematics
1 answer:
lina2011 [118]3 years ago
3 0

Answer:

V ≈ 62.83

Step-by-step explanation:

<u>Cylinder Formulas in terms of r and h</u>

Calculate the volume of a cylinder:

V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside):

L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles):

T = B = πr2

Total surface area of a closed cylinder is:

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Solution

V=πr 2h = π · 22 · 5 ≈ 62.83185

Therefore, the volume of the cylinder in the nearest tenths is V ≈ 62.83

What is the value of e^ln7 x1<br> 7e<br> 7x<br> 7
sweet-ann [11.9K]

Answer:

Both answer shown

IF it is

e^{ln 7x}= 7x

OR

IF it is

e^{ln 7}\times 1}=7

Step-by-step explanation:

Given: Little confusion is in the question

e^ln7 x1

i.e e^{ln 7x}

To Find:

e^{ln 7x}= ?

Solution:

We know Logarithmic identity as

\ln e = 1

\ln e^{x} = x

Similarly,

e^{\ln x}=x

IF it is

e^{ln 7x}= 7x

OR

IF it is

e^{ln 7}\times 1}=7\times 1=7

Adam uses coconut milk for the dessert.
VARVARA [1.3K]
Since we are already given the formula and all the information, the only thing that we have to do is input all the values and simplify until we get an answer. In addition, we must also note that the radius is 4 (because the diameter is equal to twice the radius, meaning that if the diameter is 8, the radius is 4). Using the formula and information given, we get:

Volume = 3 * (4)² * 12

Which simplifies to:

Volume = 3 * 16 * 12
Volume = 576

Now, we need to know the units. Since this is a 3d shape, and the unit for the lengths of the sides are centimeters, this answer will be in centimeters cubed. That means our answer is 576 centimeters cubed.
