What is the volume of this sphere?
Natasha_Volkova [10]

Answer:

Option c. 11,488.21 cm3

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

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

Evaluate 5x-\dfrac xy5x−
olga2289 [7]

Answer:

5x - (x/y) = 18 when x=4 and y=2

Step-by-step explanation:

5x - (x/y)

When x=4 and y=2

Substitute the value of x=4 and y=2 into the expression

5x - (x/y)

5(4) - (4/2)

Multiply 5 by 4 and divide 4 by 2

=20 - 2

Subtract 2 from 20

=18

5x - (x/y) = 18 when x=4 and y=2
