Anyone? That can help me answer these

5. 3050ft³ (rounded to 3 s.f.)

6. 4190ft³(rounded to 3 s.f.)

7. 4600ft³(rounded to 3 s.f.)

Formulas (For easier reference):

Volume of a cone: pi×r²×

Volume of cylinder: pi×r²×h

Volume of a sphere: ×pi×r³

Volume of a hemisphere: ×pi×r³

Step-by-step explanation:

You can just apply the formulas to the question:

5. Volume of cone = pi×9²×

                               = 162pi

  Volume of cylinder = pi×9²×10

                                   = 810pi

Volume of figure = 162pi+810pi

                            = 972pi

                            = 3050ft³ (rounded to 3 s.f.)

6. Volume of sphere = ×pi×10³

                                   = 1333pi

                                   = 4190ft³(rounded to 3 s.f.)

7. Volume of hemisphere = ×pi×(26÷2)³

                                          = 1464pi

                                          = 4600ft³(rounded to 3 s.f.)
