In a toy factory 200 wooden solid cylinder 7cm long and 35mm in diameter have to be painted. What is the total surface area in c

Semmy [17]

The surface area of a cylinder is:

A=2pr^2+2prh and since r=d/2

A=2p(d^2/4+dh/2)

A=(p/2)(d^2+2dh) and we need 200 of these cylinders...

A=(100p)(d^2+2dh), and using d and h, 3.5cm and 70cm we get:

A=(100p)(3.5^2+2*3.5*7)

A=(100p)(12.25+49)

A=6125p cm^2

A≈19242 cm^2 (to nearest cm^2)

How many points does the given equation have in common with the x-axis and where is the vertex in relation to the x-axis. y=x^2-

Fudgin [204]

Answer:

1. It has two points in common with the x-axis.

2. The vertex in relation to the x-axis is at $x=6$

Step-by-step explanation:

The points that the equation has in common with the x-axis are the points of intersection of the parabola with the x-axis.

To find them, substitute y=0 and solve for "x":

$y=x^2-12x+12\\0=x^2-12x+12$

Use the Quadratic formula:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-(-12)\±\sqrt{(-12)^2-4(1)(12)}}{2(1)}\\\\x_1=10.89\\\\x_2=1.10$

It has two points in common with the x-axis.

To find the vertex in relation to the x-axis, use the formula:

$x=\frac{-b}{2a}$

Substituting values, you get:

$x=\frac{-(-12)}{2(1)}\\x=6$

The diameter of a large lawn ornament in the shape of a sphere is 16 inches. What is the approximate volume of the ornament? Use

Dvinal [7]

Answer: $2143.6\ in.^3$

Step-by-step explanation:

Given: The diameter of a large lawn ornament in the shape of a sphere = 16 inches.

Then, the radius of ornament = $\frac{16}{2}=8$ inches.

We know that the volume of a sphere is given by :-

$\text{Volume}=\frac{4}{3}\pi r^3$ , where r is the radius of a sphere.

Now, the volume of the ornament is given by :-

$\text{Volume}=\frac{4}{3}(3.14) (8)^3\\\\\Rightarrow\text{Volume}=\frac{4}{3}\times3.14\times512=2143.57333333\approx2143.6\ in,^3$

Hence, the approximate volume of the ornament $=2143.6\ in.^3$
