silo has a volume of 18,840 ft³. The height of the silo is 60 ft. What is the silo's radius? Use 3.14 to approximate ππ .

1 answer:

4 0

To find r, you need to isolate it. pi*r^2*60=18,840. divide 18,840 by 60, then pi, it comes out at 100. Now find the square root to get 10

r=10

Answer:

13. c,

14. a.

Step-by-step explanation:

13. The length of a side PQ with coordinates of

P as (x,y) and Q as (w,z)

is: $\sqrt{(x-w)^{2} +(y-z)^{2} }$

so, the length of the side AB =

$\sqrt{(5-5)^{2}+(-2+7)^{2} } =\sqrt{0^{2}+5^{2} } =5$

the length of side BC =

$\sqrt{(5-1)^{2}+(-7+2)^{2} } =\sqrt{(4)^{2}+(-5)^{2} } =\sqrt{4^{2}+5^{2} }$

the length of side AC=

$\sqrt{(5-1)^{2} +(-2+2)^{2} } =\sqrt{4^{2} } =4$

now, the easiest one will be when the vertices are on the coordinate axes.

so, option c will be the most appropriate one.

14. If u see the figure clearly, the lines l and FH are parallel.

the parallel postulate, i.e, the alternate interior angles will always be congruent.

here, the alternate interior angles are angle1 and angle4.

therefore to prove this step, he used parallel postulate as a reason.

so, the correct option is "a"

3w + 7=8 need help with this

LiRa [457]

Hope this helps you out 3w+7=8

The answer is w= 1/3

Step by step:

3w+7=8
Step 1: is subtract is 7 from both sides.
3w+7-7=8-7
3w=1

Step 2: Divide both sides by 3.
3w/3 = 1/3

Your solution is:

w=1/3

Rewrite the exponential expression 25^3/2as a radical expression-<br> plss helpp

Agata [3.3K]

Answer:

$\huge\boxed{\sqrt{25^{3}}}$

Step-by-step explanation:

When we have a number to a fraction power, we need to note that

It's the same as taking the denominator root of the base to the numerator power

Basically, for example, $5^{\frac{1}{2}}$ is the same as $\sqrt{5}$ since the numerator is 1 ( $5^1 = 5$ ) and the denominator is 2 ( $\sqrt{5}$ ).

Applying this same logic to $25^{\frac{3}{2}}$ -

$25^{3}$

$\sqrt{25^3}$

Hope this helped!
