A sphere has a diameter of 14 ft. Which equation finds the volume of the sphere?

aev [14]

Answer:

The volume of the sphere is 1436 in³

The equation is

V = ⁴⁄₃ * 3.14 * (7ft)³

Step-by-step explanation:

radius = half of diameter

d = 14ft

r = 14ft / 2 = 7ft

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius = 7ft

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * (7ft)³

V = 4.187 * 343 in³

V = 1436 in³

The volume of the sphere is 1436 in³

A driver is currently at an elevation of -350 feet write an absolute value statement to express the drivers distance in feet fro

NNADVOKAT [17]

Answer:

$d = |h - 0\,ft|$ , The driver is 350 feet below sea level.

Step-by-step explanation:

The distance of the driver from the sea level is given by the following expression:

$d = |h - 0\,ft|$

$d = |-350\,ft-0\,ft|$

$d = |-350\,ft|$

$d = 350 \,ft$

The driver is 350 feet below sea level.
