Answer:

Option c. 11,488.21 cm3

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=28/2=14\ cm$ ---> the radius is half the diameter

$\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(14)^{3}$

$V=11,488.21\ cm^3$

Answer:

x = 80°

Step-by-step explanation:

Angle on a straight line = 180°

(x + 40)° + (x - 20)° = 180°

x + 40° + x - 20° = 180°

2x + 20° = 180°

2x = 180° - 20°

2x = 160°

x = 160°/2

x = 80°

Check:

(x + 40)° + (x - 20)° = 180°

(80° + 40°) + (80° - 20°) = 180°

120° + 60° = 180°

180° = 180°
