Can someone help me with this please
larisa86 [58]

The correct answer is: [D]: " 576π cm³ " .

____________________________________________________


Explanation:

____________________________________________________


Use the formula for the volume, "V", of a cylinder, to find the volume of the given cylinder:

____________________________________________________


V = π r² h ;

in which:


V = volume (for which we shall solve).

π = π ; All the answer choices given are in terms of 'π' ;


r = radius = 6 cm (given);


h = height = 16 cm (given);

__________________________________________________________

Plug in these values into the formula to solve for the volume, "V" :


V = π r² h


= π * (6 cm)² * (16 cm) ;


= π * (6²) * (cm²) * (16 cm) ;


= π * (6*6) * 16 * cm³ ;


= π * (36) * 16 * cm³ ;


= π * (36 * 16) * cm³

___________________________________________________________

V = 576 π cm³ ; which is: Answer choice: [D]: " 576π cm³ " .

A graph is shown below: A graph is shown. The values on the x axis are 0, 3, 6, 9, 12, and 15. The values on the y axis are 0, 9
Travka [436]
(0, 36) would be the point on the y axis, so 36 is the y-intercept, or the b value in the equation, y = mx + b.
(12,0) is the x-intercept, so we know the line has a negative slope.
The equation for these points would be:
y = -3x + 36
