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

1 answer:

4 0

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

A rectangle is four times as long as it is wide. The perimeter is 40 cm. Find the length of each side.

rjkz [21]

Answer:

W=4 l=16

Step-by-step explanation:

Let w = width

Let l = length

Since the length is 4 times the width, l=4w

Perimeter of rectangle = 2l + 2w

= 2(4w)+2w

=10w

The perimeter of the rectangle =40, so

40=10w and w=4

Plug w into the length equation : l=4w=4(4)=16

If MNLP, then 2 _____ 3. Choose the relationship symbol to make a true statement. < > =

storchak [24]

Answer:

The answer is > (greater than)

Step-by-step explanation:

It is > because if MN is the larger side and the largest angle would be across from the largest side, then that would make the largest angle, angle 2 and that would in turn make 3 the smaller angle. I know this is correct because I got it right.
