Answer: Volume of the bird seed feeder = 961.33 cm³

Step-by-step explanation:

Given shape of bird seed feeder of a cone

Diameter =12cm

So Radius =D/2 =12/2

=6cm

Height = 25.5cm

Volume of cone = \frac{1}{3 }\times \pi r^{2}h

Volume = \frac{1}{3}\times\pi6^{2}\times25.5

Volume =\frac{1}{3}\times \frac{22}{7}\times36\times25.5

Volume = \frac{20196}{21}

Volume = 961.33 cm³(approx)

So the volume of bird seed feeder is 961.33 cm³

The equation for the volume of a cone is: 
V= \frac{1}{3}  \pi r^{2} h
where V = volume of the cone, r = radius of the circular base, and h = height of the cone.

You are told that the height, h = 25.5 cm. You are also told that the diameter is <span>12 centimeters. Remember that the diameter of a circle is just twice the radius. Divide 12 by 2 to get the radius: r =12/2 = 6 cm.

Since you know </span>h = 25.5 cm and r = 6 cm, plug these values into your equation for volume of a cone and solve for V, volume:
V= \frac{1}{3} \pi r^{2} h\\&#10;V= \frac{1}{3} \pi (6) ^{2} (25.5)\\&#10;V \approx 961.33

------

Answer: B) <span>961.33 cm³ </span>

Which translation maps the graph of the function f(x) = x2 onto the function g(x) = x2 + 2x + 6?
Veronika [31]

Answer:

left 1 unit, up 5 units

Step-by-step explanation:

First factor

g(x)=x^2+2x+6 = (x+1)^2+5

The standard transformation formula is

g(x) = a*f(bx-h) + k

which means

a=1, b=1,h=-1, k=5

or

h=-1 means translate left one unit

k=5 means translate up 5 units.  

Choose the first option: left 1 unit, up 5 units

Answer: w= -4

Step-by-step explanation:

7w-180=52w

Subtract 7w on both sides.

-180=45w

Divide both sides by 45.

-4=w
