If the diameter of a spherical cell goes from 1 to 2 its volume goes from 0.5 to what?

The volume of a sphere is 4/3pir3 where 'pi' is 3.14 and r is radius. All you have to do is plug the new radius into the equation. Since you were given the diameter, you need to divide it in half to get the radius. Then you just need to plug in the numbers and solve:
4/3(3.14)(1)3 = 4.2
(Don't forget the units!)

What goes into and out the cell?
Waste toxins and other things the cell doesn't need goes out.
What is the main job of the cell membrane?
to control what goes in and out of a cell
What organelle controls what goes in and out of the cell?
Cell wall
What Word Goes in There As cell size goes effectiveness of diffusion and osmosis goes This drives the cells to stay small?
as a cell goes blank effectiveness of diffusion and osmosis goes bank.
What organelle helps keep the cell shape and determine what goes in and out of the cell?
Cell Wall
If the diameter of a cell goes from 1 to 2 its volume goes from 1 to?

If the diameter of a spherical cell goes from 1 to 2 its surface are goes from 3 to?
If the diameter doubles (x 2), the surface area quadruples (x 4).So if the original surface area is 3 units, the new one will be 12 units.
Is diameter and volume the same thing?
No. they are in fact very different. A circle's diameter is the length of the longest line that goes all the way across it. A three-dimensional shape has a volume, which is the amount three-dimensional space enclosed by it.
As temperature goes up volume goes?
As temperature goes up, the volume goes down
Why is a diameter always a chord but every chord is not always a diameter?
a diameter is always a chord because a chord always goes from one point of the circle to the other and a a diameter goes from one point to the midpoint
Where is the volume control on a Motorola cell phone wx345?
On the side of the phone. It's easily bumped and therefore the phone's volume often accidentally goes up or down. Very bad feature.
Why is a diameter a chord?
A diameter is a chord, because a chord always goes from one point to another in a circle, and a diameter does too.
What is the line that goes through a circle?
Diameter!
Which are the diameter lines?
the diameter line is the one from the border of a circle to another,it goes always on the center.
What does diameter mean in math terms?
A line that bisects a circle and goes through the center of it is the diameter.
Is a chord always equal to the length of the diameter?
No; actually, the diameter is a chord that goes through the center of a circle.
An automatic ice-cream scoop serves spherical helpings of ice cream. The scoop can be adjusted to serve helpings from 1 inch in diameter to 2 inches in diameter. If Tim orders a scoop with a 2-inch diameter, and if Paul wants only half as much ice cream?
THE ANSWER IS 2BECAUSE..... We have to use Tim's scoop radius to calculate his scoop volume, then divide it by 2 to find Paul's scoop volume and finally calculate its radius to get the diameter. Tim's scoop radius is diameter/2= 2 inch/2= 1 inch. So, the formula for Tim's scoop volume, i.e. volume of a sphere is 4/3*pi*(radius cubed)= 4/3*pi, because the radius 1 inch cubed is also 1. Now, Paul's scoop volume is half of Tim's, i.e. (4/3*pi)*1/2= 4/6*pi. Then, we equate this value with the formula for volume of a sphere to find Paul's scoop radius, and multiply by 2 to get the diameter, which is 2*(cube root of 1/2). I hope I said it right! ADDITIONAL DETAILS: After finding Paul's scoop volume(4/6*pi), you have to write, 4/3*pi* radius cubed= 4/6*pi(i.e. Paul's scoop volume and the volume of a sphere are the same thing, because the scoop is a sphere, isn't it?) then you can cancel out 4/3 and pi from both sides(as you should know, similar quantities can be cancelled from both sides of an equation- if both the quantities are in multiplied or divided form). That's where pi goes, and 4/3 too, and you have: radius cubed= 1/2; therefore, radius= cube root of 1/2. Hence, diameter= 2*cube root of 1/2. If you still have problems, feel free to say it.
