An infinite number of solutions since the right side is equal the left side for every value of x.

Answer:

301.44 cubic units

Step-by-step explanation:

$volume \: of \: cone \\ \\ = \frac{1}{3}\pi {r}^{2} h \\ \\ = \frac{1}{3} \times 3.14 \times {(6)}^{2} \times 8 \\ \\ = \frac{1}{3} \times 3.14 \times 36 \times 8 \\ \\ = 3.14 \times 12 \times 8 \\ \\ = 301.44 \: {units}^{3} \\ \\ \red{ \bold{volume \: of \: cone = 301.44 \: {units}^{3}}}$

If a line has a slope of 2 and contains the point (-2, 1), what is its equation in point-slope form?

Ivanshal [37]

Point slope form is y-y1= m(x-x1) where m is slope and y1 and x1 are the x and y of the coordinate given.

y-1= 2(x-(-2))
y-1= 2(x+2)

Final answer: y-1= 2(x+2)

The figure is made up of a cylinder and a hemisphere. To the nearest whole number, what is the approximate volume of this figure

Novosadov [1.4K]

Hello!

The figure is made up of a cylinder and a hemisphere. To the nearest whole number, what is the approximate volume of this figure?

Use 3.14 to approximate π .

Enter your answer in the box. in.³

Data: (Cylinder)

h (height) = 7 in

r (radius) = 2.5 in (The diameter is 5 being twice the radius)

Adopting: $\pi \approx 3.14$

V (volume) = ?

Solving: (Cylinder volume)

$V = \pi *r^2*h$

$V = 3.14 *2.5^2*7$

$V = 3.14*6.25*7$

$V = 137.375 \to \boxed{V_{cylinder} \approx 137.38\:in^3}$

Note: Now, let's find the volume of a hemisphere.

Data: (hemisphere volume)

V (volume) = ?

r (radius) = 2.5 in (The diameter is 5 being twice the radius)

Adopting: $\pi \approx 3.14$

If: We know that the volume of a sphere is $V = 4* \pi * \dfrac{r^3}{3}$ , but we have a hemisphere, so the formula will be half the volume of the hemisphere $V = \dfrac{1}{2}* 4* \pi * \dfrac{r^3}{3} \to \boxed{V = 2* \pi * \dfrac{r^3}{3}}$
