Answer:


V=1767

Explanation:

Step 1: Find the volume of the sphere

Volume of a Sphere:
V=(4)/(3)\pi r^(3)

Find the radius


Radius = Diameter / 2


Radius = 15 / 2

Plug in the values and solve


V=(4)/(3)\pi * (15)/(2)^(3)


V=(4)/(3)\pi * (3375)/(8)


V=(1125)/(2)\pi


V=1767

Answer:
V=1767

Answer:

1766 using 3.14 for pi

1767 using the pi button

Explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

we need to know the radius

r =d/2 = 15/2 = 7.5

V = 4/3 (pi)( 7.5)^3

V =562.5 pi

Approximating pi by 3.14

V = 562.5 (3.14)

V =1766.25

To the nearest whole number

V = 1766

If you use the pi button

1767.14586

To the nearest whole number

1767
