Answer:

A. 2.9π(9²)

Step-by-step explanation:

You are expected to know that the area of a circle is given by the formula ...

A = πr²

and that r in the formula represents the radius of the circle, half the diameter.

The area of the circular base of the cylinder is the area of a circle with a radius of 9 feet. It will be ...

A = π(9²)

When that is multiplied by the height of the cylinder to find its volume, you have ...

V = Bh

V = (π(9²))(2.9)

This can be rearranged to match the form in answer choice A:

2.9π(9)²

Whats (8,2) and (9,3) in finding the slope from points

igor_vitrenko [27]

A (8, 2)
B (9, 3)
$m = \frac{yb - ya}{xb - xa}$
$m = \frac{3 - 2}{9 - 8}$
$m = \frac{1}{1}$
$m = 1$

Answer: A.(3x,3y)

Step-by-step explanation:

In the given graph,

Triangle A'B'C' is an image of Triangle ABC after dilation.

Algebraic rule for dilation (with center =origin)

$(x,y)\to (kx,ky)$ , where k= scale factor.

Coordiantes of A = (1,1) Coordinates of A' = (3,3)

Scale factor = $\dfrac{\text{x-coordinate in image}}{\text{ x-coordinate in pre-image}}$

$=\dfrac31=3$

Hence, the required algebraic rule : (3x,3y)

The correct option is A.

Well on this problem recall area of a rectangle is defined by:

A = lw our w = 1/6 and our l = (x + $\frac{2}{3}$ ) we have let 'x' represent our original length.
$(x + \frac{2}{3} )( \frac{1}{6} )= \frac{11}{72}$
$\frac{1}{6} x+ \frac{2}{18} = \frac{11}{72}$
12x + 8 = 11
12x = 11 - 8
12x = 3
x = $\frac{3}{12} = \frac{1}{4}$ So our original length is $\frac{1}{4}$
