Answer:

1. 12.6  2. 21.4

Step-by-step explanation:

1. c=2piR, so if the radius is 2, then 2 times 2 then times 3.14= 12.6(rounding to the nearest tenth)

2.i already explained the formula, so it should be 3.4*2 then times 3.14= 21.4

What is the volume of this rectangular prism?
sergiy2304 [10]

Answer:

V =\frac{12}{5}\ cm^3

Step-by-step explanation:

<u>The Volume of Rectangular Prism</u>

Given a rectangular prism of dimensions W, L, and H, its volume is the product of the three dimensions:

V = WLH

The figure shows the dimensions:

L=3 cm

W=\frac{4}{3}\ cm

H=\frac{3}{5}\ cm

Thus, the volume is:

V =3*\frac{4}{3}*\frac{3}{5}\ cm^3

V =\frac{36}{15}\ cm^3

Simplifying:

\boxed{V =\frac{12}{5}\ cm^3}

Four ninths plus nine eighteenths :]
goldenfox [79]

Answer:  17/18

In words, this is seventeen eighteenths

==========================================

Work Shown:

4/9 + 9/18

8/18 + 9/18 ... see note below

(8+9)/18

17/18

----------------

note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.

The diagram below shows a visual representation of why 4/9 = 8/18.

In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.

What is the zeros of the quadratic function y=x^2+14x+24
777dan777 [17]

Step-by-step explanation:

{x}^{2}  + 14x + 24 = 0 \\  {x}^{2}  + 12x + 2x + 24 = 0 \\ x(x + 12) + 2(x + 12) = 0 \\ (x + 12)(x + 2)  = 0\\ x =  - 12 \\ x =  - 2
