REALLY need help with this problem please

Step-by-step explanation:

A hemisphere is defined as a three-dimensional shape that is half of a sphere with exactly one flat side and a circular surface on the other side.

The volume of a sphere is evaluated by the formula

                                                      ,

where is the radius of the sphere.

Following the definition of the hemisphere, the volume is then calculated as

                                                      .

Therefore,

                                               .

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
