Given a sphere with a radius of 7.5 ft.

ad-work [718]

Answer:

volume of the sphere is V=1766.25 $ft^{3}$

Step-by-step explanation:

step:1

<u>The volume of the sphere formula is V= $\frac{4 pi r^{3} }{n}$ </u>

Given radius of the sphere r=7.5 ft

substitute given radius r=7.5 ft value in volume of the sphere formula

$V=[tex]\frac{4 pi r^{3} }{n}$ \\

V=\frac{4(3.14)(7.5)^{3} }{3}[/tex]

V=1766.25 $ft^{3}$

Final answer is V=1766.25 $ft^{3}$

There are only chickens and pigs in Henry's Barn Henry counted a total of Sixteen animal heads and a total of 50 animal feet.How

raketka [301]

Answer:

9 pigs

Step-by-step explanation:

We have the following numbers of heads:

pigs (p) + chickens (c) = 16 animal heads (1)

And the following numbers of feet:

4p + 2c = 50 animal feet (2)

From equation (1):

p = 16 - c (3)

By entering equation (3) into (2) we have:

4(16 - c) + 2c = 50

64 - 4c + 2c = 50

c = 7

Now, entering the value of c into equation (3) we have the next value of p:

p = 16 - c

p = 16 - 7

p = 9

Therefore, the number of pigs that Henry has is 9.

I hope it helps you!
