Answer:

2. 8/5

Step-by-step explanation:

It is 8/5 because to find the slope for (4, -7) and (9, 1), you just need to find the difference. So you do 9-4= 5 and then 1- (-7)= 8, and since it is y over x, you put 8 over 5 and get 8/5.

The volume of the sphere is 904.32 m. To the nearest meter, what is the radius of the sphere????? Use 3.14 for pi.

Rus_ich [418]

Answer:

Step-by-step explanation:

The formula for the volume of a sphere is $\frac{4}{3} \pi r^3$ . Plugging in the values that you are given, you get:

$904.32=\frac{4}{3}\pi r^3$

Dividing both sides by pi or 3.14:

$288=\frac{4}{3}r^3$

Dividing both sides by 4/3:

$216=r^3$

Taking the cube root of both sides:

$r=6$

|HJ|=20/3 pi

|HJ|=4/9pi÷360.pi.r^2

20/3=4/9÷360.pi.r^2

20.270÷pi=r^2

5400÷3=r^2

1800=r^2

r=30 square root of 2
