Please explain and answer

krek1111 [17]

Step-by-step explanation:

$v \: = \: \pi \: {r}^{2} \times \frac{h}{3}$

rearrange to get

$48\pi \: = \: \pi {r}^{2} \times \frac{9}{3}$

remove pi from both sides

$48 \: = {r}^{2} \: \times 3$

$\frac{48}{3} = {r}^{2}$

$16 = {r}^{2}$

$r = \sqrt{16}$

$r = 4$

Can u plz add these together.

Rainbow [258]

Answer:

1. -3

2. 7

3. -2

4. 3

Step-by-step explanation:

1. idk

2. 3.2 move 3b over to get 3.2-3b-4.7=-3.3 move 4.7 over to get

3.2b-3b=4.7-3.3 now 3.2b-3b=.2b and 4.7-3.3=1.4 .2b/.2=b 1.4/.2=7 so b=7

3. 4.6y-y+4=y-1.2 now switch the 4 and the y to read 4.6y-2y=-4-1.2

2.6y=-5.2 divide both sides by 2.6 to get y=-2

4. 7.5c-2.5c+8=-7 move 8 to other side to get 7.5c-2.5c=-8-7

5c=-15 divide both sides by 5 getting c=3
