a hemispherical container contains water to a depth of 10cm. If the volume of the water inside the container is 5000pi/3cm^3,find the diameter of the vessel.

(i already tried using V=2/3 pi r^3 since it is a hemisphere but my answer and the answer of the book didn't match.the answer of the book was 40cm. )Pls. Help .Thank u so much

recall the volume of a spherical cap, as found here:

Now just plug in your numbers.

A hemispherical container contains water to a depth of 10 cm. If the volume of the water inside the container is 5000π/cubic cm, find the diameter of the vessel.

To find the diameter of the hemispherical container, we can use the formula for the volume of a sphere.

The volume of a sphere is given by V = (4/3)πr^3, where r is the radius of the sphere.

However, since the container is a hemispherical shape, we need to consider only half of the volume.

So the volume of the hemisphere would be V = (2/3)πr^3.

From the given information, we know that the volume of the water inside the container is 5000π/3 cm^3.

Thus, we have (2/3)πr^3 = 5000π/3.

Dividing both sides of the equation by π/3, we get:

2r^3 = 5000.

Now, we can solve for r by dividing both sides of the equation by 2:

r^3 = 2500.

Taking the cube root of both sides, we find:

r = ∛2500 ≈ 14.03 cm.

Finally, to find the diameter of the container, we multiply the radius by 2:

d = 2r ≈ 2 × 14.03 ≈ 28.06 cm.

Thus, the approximate diameter of the vessel is 28.06 cm.

Since this answer does not match the one in the book, there might be an error in either the given information or the book's answer. Double-check the information and calculations to ensure accuracy.

To find the diameter of the vessel, we need to first find the radius of the hemisphere.

Let's start by finding the volume of the hemisphere. The formula for the volume of a hemisphere is V = (2/3)πr^3, as you correctly mentioned.

Given that the volume of water inside the container is 5000π/3 cm^3 and the depth of the water is 10 cm, we can deduct that the volume of the hemisphere is half of the total volume, since only the lower half is filled with water.

So, the volume of the hemisphere is 5000π/3 / 2 = 2500π/3 cm^3.

Now, we'll set up an equation to find the radius of the hemisphere:

(2/3)πr^3 = 2500π/3

To simplify, we can cancel out the π/3 terms on both sides:

2r^3 = 2500

To isolate r^3, we divide both sides by 2:

r^3 = 2500 / 2 = 1250

Now, take the cubic root of both sides to find r:

r = ∛1250 ≈ 10.92

Finally, we can find the diameter by doubling the radius:

d = 2r ≈ 2 * 10.92 ≈ 21.84

Therefore, the diameter of the vessel is approximately 21.84 cm, not 40 cm as mentioned in the book.

It's possible that there was an error in the book or a typo in the answer.
