The height of a cylinder is twice the radius of its base.
Ber [7]

Let x represent radius of circle.

We have been given that the height of a cylinder is twice the radius of its base. So height of cylinder would be 2x.

Now we will use volume of cylinder formula to our given problem.

V=\pi r^2h, where,

r = Radius of base of cylinder,

h = Height of cylinder.

Upon substituting our given values, we will get:

V=\pi\cdot x^2\cdot 2x

V=2x^3\pi

Therefore, our required volume expression would be 2x^3\pi.

Use the midpoint formula to estimate the sales of Cars, Inc. in 2009, given the sales in 2008 and 2010. Assume that the sales of
lana [24]

Answer:

<em>The estimated sales were $260 million</em>

Step-by-step explanation:

Assume the endpoints of a segment are (x1,y1) and (x2,y2).

The midpoint (xm,ym) is calculated as follows:

\displaystyle x_m=\frac{x_1+x_2}{2}

\displaystyle y_m=\frac{y_1+y_2}{2}

The sales ov Cars, Inc. were (2008,240 million) and (2010,280 million). We need to use the midpoint to estimate the sales in 2009:

\displaystyle x_m=\frac{2008+2010}{2}=2009

\displaystyle y_m=\frac{240+280}{2}=260

The estimated sales were $260 million

circle centered at the origin has a radius of 5 units. The terminal side of an angle, θ, intercepts the circle in Quadrant IV at
astraxan [27]

Answer:

Step-by-step explanation:

x²+y² = 5²

3²+y² = 25

y² = 16

y = ±√16 = ±4

Since the terminal side is  in quadrant IV, y = -4

sinθ = -4/5
