sum of interior angles=(n-2)×180=(5-2)×180=3×180=540

72+2x+99+89+3x=540

5x+ 260=540

5x=540-260

5x=280

How many cubic centimeters of water can this paper cone cup hold?

blagie [28]

48π cm^3

Step-by-step explanation:

The formula for the volume of a cone is...

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

We can plug everything we know from the photo into the equation, but note that the picture gives us the diameter, which is 8, instead of the radius. The radius is half of the diameter, so the radius will be 4. Also we will be leaving pi as it is, instead of changing it to 3.14.

$V=\frac{1}{3}*(\pi *4*4*9)$

$V=\frac{1}{3}*(144\pi )$

V = 48π

The paper cone can hold 48π cubic centimeters of water.

Given the following functions f(x) and g(x), solve f[g(10)] and select the correct answer below: f(x) = 10x + 8 g(x) = x + 9 2,0

ikadub [295]

ANSWER
$f(g(10)) = 198$

EXPLANATION

The given functions are;

$f(x) = 10x + 8$
and

$g(x) = x + 9$

To find
$f(g(10))$
we need to find

$f(g(x)) = f(x + 9)$

$f(g(x)) =10(x + 9) + 8$

$f(g(x)) =10x + 90 + 8$

$f(g(x)) =10x + 98$

$f(g(10)) = 10(10) + 98$

$f(g(10)) = 100 + 98$

$f(g(10)) = 198$

The last option is the correct answer
