Acylinder has a base radius of 2 inches and a height of 9 inches what is the volume in cubic in to the nearest tenth place.

113.1 cubic inches

Step-by-step explanation:

The volume of a cylinder is given by the formula:

Where

V is the volume

r is the radius

h is the height

Given, h = 9 and r = 2, we substitute and find the volume:

We need answer to nearest tenth, that is 1 decimal place, so we round of the answer as:

113.1 cubic inches

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

the correct answer is 5 6 and 7
