Answer:

Please see the attached picture for the full solution.

*From the 4th line of the 1st image, you could also expand it using

(a +b)²= a² +2ab +b² and

(a -b)²= a² -2ab +b².

When squaring a fraction, square both the denominator and numerator.

➣(a/b)²= a²/b²

The volume of a sphere is 5000 pi m 3 what is the surface area

Nikitich [7]

$V = \frac{4}{3}\pi r^3
\\ 5000\pi = \frac{4}{3} \pi r^3
\\ 5000 = \frac{4}{3} r^3
\\ \frac{3}{4} * 5000 = r^3
\\ 3750 = r^3
\\ r = 15.536
\\ SA = 4 \pi r^2
\\ SA = 4\pi (15.536)^2
\\ SA = 3033.11$

A silo is not the shape of a cone. The silo is 8 meters tall and it's base has a diameter of 3 meters. Soybeans cost $414 per cu

Gnom [1K]

Answer:

$7803.72

Step-by-step explanation:

We have been given that a silo is in the shape of a cone. The silo is 8 meters tall and it's base has a diameter of 3 meters. Soybeans cost $414 per cubic meter. We are asked to find the total cost to fill the silo with soybeans.

First of all, we will find the volume of silo using volume of cone formula.

$\text{Volume of cone}=\frac{1}{3}\pi r^2 h$ , where,

r = radius

h = Height

We know that radius is half the diameter, so radius of silo would be $r=\frac{3}{2}=1.5$ .

$\text{Volume of cone}=\frac{1}{3}\pi (1.5\text{ m})^2 (8)\text{ m}$

$\text{Volume of cone}=\frac{1}{3}\pi\times 2.25\text{ m}^2 (8)\text{ m}$

$\text{Volume of cone}=\pi\times 0.75\text{ m}^2 (8)\text{ m}$

$\text{Volume of cone}=\pi\times 6\text{ m}^3$

$\text{Volume of cone}=18.8495559\text{ m}^3$

Now we will multiply total volume by $414 to find total cost.\

$\text{Total cost of soybeans}=\$414 \times 18.8495559$

$\text{Total cost of soybeans}=\$7803.7161426$

$\text{Total cost of soybeans}\approx \$7803.72$

Therefore, it will cost $7803.72 to fill the silo with soybeans.

Compute the probability of randomly selecting a three or club.

Pavlova-9 [17]

Find the total number of cards in a deck. Count all the # 3’s total cards/#3 cards
Count all the clubs total card/ clubs
Not sure if you are counting 3’s & clubs together. If you are, total cards/ both
So all you have to do is count & then divide to get the probability.
