If the quarter circle intersects the x-axis at the coordinate (- 3, 0) and is rotated around the y-axis what is the resulting 3 - D figure and determine its volume to the nearest cubic unit.

Volume of the hemisphere will be 57 cubic units.

Step-by-step explanation:

A quarter circle which intersects the x-axis at (-3, 0) when rotated around the y-axis, 3-D figure formed will be a hemisphere.

As shown in the figure attached,

Radius of the hemisphere formed = 3 units

Volume of the hemisphere =

                                             =

                                             =

                                             = 18π

                                             = 56.55 cubic units

                                             ≈ 57 cubic units

Therefore, volume of the hemisphere will be 57 cubic units

1e+27

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3
