Answer:

Step-by-step explanation:
<u>Geometric Sequences</u>
The geometric sequence is given as:

Where n is the number of the term, n≥1, and r is the common ratio.
The sum of n terms of the geometric sequence is given by:

We are given: S3=252, a1=192, thus substuting:

Dividing by 12:

Recall that:

Substituting:

Both solutions are valid
Step-by-step explanation:
liters
The capacity of a container is the volume of a container measured in liquid units. Cups, pints, quarts, and gallons are customary units of measurement. Two metric units of capacity are milliliters and liters. A milliliter is equal to about 20 drops from an eyedropper.
Answer:
V = 2143.57 cm^3
Step-by-step explanation:
We want to find the volume of the sphere
V = 4/3 pi r^3 where r is the radius and pi = 3.14
V = 4/3 ( 3.14) ( 8)^3
V = 2143.57333 cm^3
Rounding to the nearest hundredth
V = 2143.57 cm^3
