What is the volume of the cylinder below? Use 3.14 for pi and I round to the nearest tenth

Rainbow [258]

Answer:

Option (4).

Step-by-step explanation:

Formula to calculate the volume of a cylinder is,

V = πr²h

Here r = radius of the cylinder

h = Height of the cylinder

From the figure attached,

r = $\frac{13}{2}=6.5$ cm

h = 11 cm

Now we substitute the values of h and r in the formula,

V = π(6.5)²(11)

= 464.75π

= 1459.32

≈ 1459.3 cm³

Therefore, volume of the given cylinder is 1459.3 cm³

Option (4) will be the answer.

Find the centroid of the region bounded by y = 3x^2, y = 0, x = 4

ANTONII [103]

To determine the centroid, we use the equations:

x⁻ = 1/A (∫ (x dA))
y⁻ = 1/A (∫ (y dA))

First, we evaluate the value of A and dA as follows:

A = ∫dA
A = ∫ydx
A = ∫3x^2 dx
A = 3x^3 / 3 from 0 to 4
A = x^3 from 0 to 4
A = 64

We use the equations for the centroid,
x⁻ = 1/A (∫ (x dA))
x⁻ = 1/64 (∫ (x (3x^2 dx)))
x⁻ = 1/64 (∫ (3x^3 dx)
x⁻ = 1/64 (3 x^4 / 4) from 0 to 4
x⁻ = 1/64 (192) = 3

y⁻ = 1/A (∫ (y dA))
y⁻ = 1/64 (∫ (3x^2 (3x^2 dx)))
y⁻ = 1/64 (∫ (9x^4 dx)
y⁻ = 1/64 (9x^5 / 5) from 0 to 4
y⁻ = 1/64 (9216/5) = 144/5

The centroid of the curve is found at (3, 144/5).

Really could use help here.

marishachu [46]

Answer:

$\mathsf {y =\frac{15}{7}x }$ < $\mathsf {y=\frac{13}{6}x }$ < $\mathsf {y=\frac{11}{5}x }$ < $\mathsf {y=\frac{21}{9}x }$ < $\mathsf {y= \frac{19}{8}x}$

Step-by-step explanation:

Finding the unit rate of the graph :

Take 2 points and find the slope
⇒ (0,0) and (12, 25)
⇒ m = 25 - 0 / 12 - 0
⇒ m = 25/12
The equation is : y = 25/12x

Now, the equations with greater unit rates (in increasing order) are :

$\mathsf {y =\frac{15}{7}x }$ < $\mathsf {y=\frac{13}{6}x }$ < $\mathsf {y=\frac{11}{5}x }$ < $\mathsf {y=\frac{21}{9}x }$ < $\mathsf {y= \frac{19}{8}x}$
