Using number line and mental mathematics, the value of u = -√25, t = - 2π, s = -√68
<h3>What is a number line?</h3>
A horizontal line with evenly spaced numerical increments is referred to as a number line. How the number on the line can be answered depends on the numbers present.
The usage of the number is determined by the question that it corresponds to, such as when graphing a point.
As we can observe that
All the points lie on negative axis. The value of u = -√25 = 5
t = -2π = -2×3.14 = -6.28
s = -√68 = - 8.24

Answer:

Step-by-step explanation:
Given
Shapes: Cube and Cone
Required
Determine the volume
First we calculate the volume of the cube

Where
l = side length = 5.1


Next, calculate the volume of the cone using:

Where
h = 5.1



So, we have:





The volume of the figure is:




Four Hundred Ninety two thousand Fifty Three.
