Find the volume of the prism. Round to the nearest tenth if necessary.

Answers

The volume of a prism = the area of the base × the prism's height
$V=Bh$

Our base is a triangle, which has this area formula:
The area of a triangle = 1/2 × the triangle's base × the triangle's height
$A=\frac12bh$

Let's plug in 6 for the base of our triangle and 5.2 for its height.
$A=\frac12*6*5.2$
Crunch some numbers...
$A=15.6$

Now that we know the area of the base, let's find the volume of our prism.
$V=Bh$
Let's plug in 15.6 for the area of the base and 9 for the height of the prism.
$V=15.6*9$
Crunch some more numbers...
$V=140.4$
Remember to add your units!

$\boxed{V=140.4\ m^3}$

How many inches is 78% of 3 feet?

Please show me how to do it!

Answers

Answer:

28.08 inches

Step-by-step explanation:

Recall 1 foot = 12 inches

3 feet = 12 x 3 inches = 36 inches

78% of 3 feet

= 78/100 x 3 feet

= 78/100 x 36 inches

= 28.08 inches

If an ant runs randomly through an enclosedcircular field of radius 2 feet with an inner circle of
radius 1 foot, what is the probability that the ant will
be in the inner circle at any one time?
a.1/8
b 1/6
c 1/4
d.1/2
e 1

Answers

The area of a circle is π (radius²)

The area of the outer (2-ft) circle is π (2²) = 4 π square feet.

The area of the inner (1-ft) circle is π (1²) = 1 π square feet.

The inner circle covers 1/4 of the area of the outer circle.

So if the ant wanders around totally aimlessly and randomly, and there's no way to
know where he came from, where he is now, or where he's going next, and there's
an equal chance of him being anywhere in the big circle at any time, then there's a
25% chance of him being inside the small circle at any time, because 1/4 of the
total area is in there.

That's choice c).
