Hello there.

A ball has a radius of 18 cm.

What is the approximate volume of the ball?

Answer:

The approximate volume of the ball is, 24,416.64 cubic cm

Step-by-step explanation:

Volume of a sphere is given by:

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

where,

V is the volume of the sphere

r is the radius of the sphere.

As per the statement:

A ball has a radius of 18 cm

⇒ $r = 18 cm$ and use $\pi = 3.14$

Substitute these in [1] we have;

$V = \frac{4}{3}\cdot 3.14 \cdot (18)^3$

⇒ $V = \frac{4}{3} \cdot 18,312.48$

Simplify:

$V = 24,416.64 cm^3$

Therefore, the approximate volume of the ball is, 24,416.64 cm^3

Create your own real-world problem which uses either an arithmetic or geometric sequence to solve it. Include the solution, with

yanalaym [24]

Let's say that you're in your room and you find that the current temperature of 72 degrees is too cold, so slowly you increase the temperature of the room by two degrees.

We know that the explicit formula is
a^n=a^1+ (n-1)d

and so by substituting the given information in

a^n= 72 + (n-1)2

a^1=Initial temp
d= rate of change

by substitution a value of n (the term we are looking for) into this equation, you can then calculate the temperature that you just set the room too.
