Find the volume of a sphere that has a surface area of 16 * pi sq. in.

You can use this formula to solve this problem... it uses the surface area to find the volume.

V= (A^3/2)/(6√pi)   

Substitute the surface area value into "A" and then solve as you would on paper. I'm sorry I couldn't show you the entire process but this should get you your answer. Plus if your teacher asks for work, I just set you up and everything else should be self explanatory.  

But the answer is >  33.5 inches cubed

1.0

Step-by-step explanation:

0.989 broken down to place values:

0 (ones)

.

9 (tenths)

8 (hundredths)

9 (thousandths)

In this case, you rounded 0.989 to 0.99. By the looks of it, you rounded to the hundredths place, which is correct. The thousandths place value was a 9, and as 9 is greater than 5, you round up.

0.989 rounded to the nearest hundredths is 0.99.

If you are rounding to the tenths, note that the tenths place value is a 9. Look at the hundredths value. It is an 8. Because 8 is greater than 5, round up.

0.989 rounded to the nearest tenths is 1.0

Why?

You are rounding to the nearest tenths. As 8 is greater than 5, you round up, adding 1 to the tenths place value.

0.9 + 0.1 = 1.0

Therefore, your answer is 1.0
