Answer: 12 hours a week

The volume of a cone with a height of 4 cm is 12π cubic cm. What is the radius of the base?
blondinia [14]

Answer:

r = 6cm

Step-by-step explanation:

Solve for r:

v =  \frac{1}{3} \pi {r}^{2}

12\pi =  \frac{1}{3} \pi {r}^{2}  \\ 12\pi =  \frac{\pi {r}^{2} }{3}  \\ 3 \times 12\pi = \pi {r}^{2}  \\ 36\pi = \pi {r}^{2}  \\  \frac{36\pi}{\pi}  =  \frac{\pi {r}^{2} }{\pi}  \\  \sqrt{ {r}^{2} }  =  \sqrt{36}  \\ r = 6

4= 6/a + 5 solve for x
Scorpion4ik [409]

Answer:

a=-6

Step-by-step explanation:

4= 6/a + 5

Subtract 5 from each side

4-5= 6/a + 5 -5

-1 = 6/a

Multiply by a on each side

-1*a = 6/a *a

-a =6

Multiply by -1

a= -6

Write the ratio as a fraction in simplest form.<br><br> 10.8 seconds : 36 feet <br><br> (Show work)
vodka [1.7K]

Answer: Ratio as a fraction in simplest form is :

\frac{27}{1}=27

Step-by-step explanation:

Since we have given that

10.8 seconds : 36 feet

As we know that

1\ second=\frac{1}{60}\ mile\\\\1\ second=90\ feet

So, we use it :

10.8 seconds : 36 feet

=10.8\times 90\ feet:36\ feet\\\\=972:36\\\\=27:1

Hence, Ratio as a fraction in simplest form is :

\frac{27}{1}=27
