If h = 18 units and r = 8 units, then what is the volume of the cone shown above? A. B. C. D.

katen-ka-za [31]

1,205.76 units^3 or 384 π

The formula for the volume of a cone is:

$V=\frac{1}{3}\pi r^2 h$

We can plug in.

$V=\frac{1}{3}*3.14*8*8*18$

= 1,205.76 units^3

If you are looking for the exact answer, we will leave π.

$V=\frac{1}{3}*\pi*8*8*18$

= 384 π

Write an equation and solve for the missing anglemeasure.

Zepler [3.9K]

Answer:

Equation: $143 + g = 180$

$g =37$

Step-by-step explanation:

Given

The attached figure

Required

The equation to find g and the solution

From the attached: Angles ACD, DCE and ECB lie on a straight line.

Where

$ACD = 90$ $DCE = 53$ $ECB = g$

This means that:

$ACD + DCE + ECB = 180$

$90 + 53 + g = 180$

$143 + g = 180$

Subtract 143 from both sides

$-143 + 143 + g = 180 - 143$

$g = 37$
