Answer:

volume=2304\pi mm^3

volume = 7234.56 mm^3

Step-by-step explanation:

Radius , r = 12mm

Volume=\frac{4}{3}\pi r^3=\frac{4}{3}\pi (12^3)

                     =\frac{4}{3} \pi*1728

                     =4\pi *576

                     =2304\pi mm^3

                     or

                     =7234.56 mm^3

Will mark brainliest! Please help!
ValentinkaMS [17]

Answer:

The dimensions are:

3(2x+1) by (7x+5)

Step-by-step explanation:

The area of the rectangle is given as

A=42x^2+51x+15

The factored form of this quadratic trinomial gives the dimensions of the rectangle.

We factor 3 first to obtain;

A=3(14x^2+17x+5)

We split the middle term to get;

A=3(14x^2+10x+7x+5)

We factor within the parenthesis to get;

A=3(2x(7x+5)+1(7x+5))

We factor further to get;

A=3(2x+1)(7x+5)

The dimensions are:

3(2x+1) by (7x+5)

Then the perimeter will be

2(6x+3+7x+5)=26x+16\:\:\:\boxed{\sqrt{} }

What do I type in the box pls help???
MaRussiya [10]

Answer:

f(x)=3x-5

g(x)=-6x²+6x+2

f(x)×g(x)

=(3x-5)(-6x²+6x+2)( use distributive property)

=(3x×-6x²)+(3x×6x)+(3x×2)+(-5×-6x²)+(-5×6x)+(-5×2)

=(-18x³)+(18x²)+6x+30x²-30x-10

=-18x³+18x²+6x-30x+30x²-10

=-18x³+18x²-24x+30x²-10

=-18x³+18x²+30x²-10

=-18x³+48x²-10---------------you may write this answer

Hope it's was clear,

One side of a rectangle is three times as long as another. If its area is 363 square centimeters, find its dimensions.
Yakvenalex [24]

9514 1404 393

Answer:

  11 cm by 33 cm

Step-by-step explanation:

You can solve this problem mentally as follows.

Consider the rectangle as 3 squares, side-by-side. Then the area of each of those squares is 363/3 = 121 cm^2. From your knowledge of the squares of numbers, you know that 121 = 11^2. So, the width of the rectangle is 11 cm, and the length is 3 times that, or 33 cm.

_____

Using variables, we can let w represent the width. Then 3w can represent the length, and the area is ...

  A = LW

  A = (3w)(w) = 3x^2 = 363

  w^2 = 363/3 = 121

  w = √121 = 11

  3w = 3·11 = 33

The width is 11 cm; the length is 33 cm.

Line AB is tangent to circle O at A. The diagram is not drawn to scale.
Arlecino [84]
AO = 21
BC = 14
OC = radius of the circle = AO = 21
∴ OB = OC + CB = 21 + 14 = 35
<span>Line AB is tangent to circle O at A</span>
∴ AB is perpendicular to AO
∴ Δ OAB is a right triangle at A
Applying Pythagorean theorem
∴  OB² = AO² + AB²
∴ AB² = OB² - AO² = 35² - 21² = 1225 - 441 = 784
∴ AB = √784 = 28
