Mk, someone knows this answer. I know it! Pwease help!

rosijanka [135]

Answer:

16(base) x 15(height) x 1/2(basically just dividing by 2) = 120

120 x 2 = 240

17 x 17 = 289, 289 x 2 = 578

17 x 16 = 272

Add all given areas:

240 + 272 + 578 = 1,090 in2 is your answer

The height of a cone is equal to the diameter of the base. What expression represents the volume of the cone, in cubic units?

Maurinko [17]

By definition, the volume of a cone is given by:
$V = (1/3) * (\pi) * (r ^ 2) * (h)
$
Where,
r: radius of the circular base
h: height of the cone
Let's define a variable:
x: diameter of the base
We have then that the radio is:
$r = x / 2
$
The height is:
$h = x
$
Substituting values:
$V = (1/3) * (\pi) * ((x / 2) ^ 2) * (x)
$
Rewriting:
$V = (1/3) * (\pi) * (x ^ 2/4) * (x)

V = (1/12) * (\pi) * (x ^ 3)$
Answer:
An expression that represents the volume of the cone, in cubic units is:
$V = (1/12) * (\pi) * (x ^ 3)$
