Question

The drawing tip of a large marker is in the shape of a hemisphere. The diameter of the great circle of the hemisphere is 22

millimeters. What is the volume of the drawing tip? (Use 3.14 for 7. Round the answer to the nearest tenth, if necessary. Recall
that the formula for the volume of a sphere is V = 1 )
1,393.1 cubic millimeters
2,786.2 cubic millimeters
5,572.5 cubic millimeters
8,358.7 cubic millimeters

Answer 1

B.

Explanation:

Answer 2

The volume of the hemisphere for the given diameter is 2,786.2 millimeter³ .

Explanation:

Given as :

The diameter of the hemisphere = D = 22 millimeter

The radius of the hemisphere = R =
`(\textrm Diameter)/(2)`

Or, R =
`(22)/(2)` = 11 millimeter

Now, The volume of hemisphere = V =
`(2)/(3)`×
`\pi`×R³

Where R is the radius of hemisphere

And The value of
`\pi` is 3.14

Now , V =
`(2)/(3)`×3.14×(11)³

or, V =
`(2)/(3)`×3.14×1331

∴ V = 2,786.2 millimeter³

So The volume of hemisphere = 2,786.2 millimeter³

Hence The volume of the hemisphere for the given diameter is 2,786.2 millimeter³ . Answer
