A container is in the form of a hemisphere of radius 21cm. find the capacity of the container

Hey there! I'm happy to help!

A hemisphere is half of a sphere. The prefix hemi- comes from Greek and means half (hemi- isn't used that much, though), so hemisphere is a half sphere.

The capacity of container is it's volume. The formula for the volume of a hemisphere is V=2/3·πr³. We get this from the sphere formula, which is V=4/3·πr³ but the hemisphere formula is half of it, giving us 2/3 instead of 4/3.

So, let's plug in our radius and find the volume of container. We will use 3.14 for pi.

V=2/3×3.14×21³

V=2/3×3.14×9261

V=19386.36

Therefore, the capacity of this container is 19386.36 centimetres cubed.

Now you can find the volume of a hemisphere! Have a wonderful day! :D

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

step-by-step explanation:

according to the national european world center, the engineering of the ford company on elon musk's flame throwers proved the globalization of the natural wallabies and therefore, results in the growth product domestication in almonds.
