Find the altitude of a regular tetrahedron whose volume is 486 square root of 2 cm^3.

1 answer:

6 0

Using the formula:
V = a^3 / 6 square root of 2
h = square root 2/3 x a

h = 2/3 x 3%
V^1/3 = 2/3 x 3% x 486^2/3 = 13.09348

I hope this answer helps. Looking forward to help you again. Have a great day!

adell [148]

Answer:

$h=\frac{6V}{\pi d^2}$

Step-by-step explanation:

we have

$V=\frac{\pi d^2h}{6}$

Solve for h

That means ----> isolate the variable h

step 1

Multiply by 6 both sides

$6V=\pi d^2h$

step 2

Divide by $\pi d^2$ both sides

$h=\frac{6V}{\pi d^2}$

Evaluate v(x)=12-2x-5 when x=-2,0, and 5 . v(-2)= v(0)= v(5)=

Vaselesa [24]

Step-by-step explanation:

v(-2)= 12-2x(-2)-5

=12+4-5

=16-5

=11

v(0)= 12-2x0-5

= 12-0-5

=12-5

v(5)= 12-2x5-5

= 12-10-5

=12-5
