Rearrange the product
(5.91 * 10^(-3)) * (8.7 * 10^10)
as
(5.91 * 8.7) * (10^(-3) * 10^10)
We have 5.91 * 8.7 = 51.417, and 10^(-3) * 10^10 = 10^(10 - 3) = 10^7, so the original product above reduces to
51.417 * 10^7
We can "add" powers of 10 by moving the decimal place to the left:
51.417 = 5.1417 * 10
so that
51.417 * 10^7 = (5.1417 * 10) * 10^7 = 5.1417 * 10^8
Answer:
8000
Step-by-step explanation:
top: 20 * 2 / 2 *40 = 800
bottom: 20 * 40 * 9 = 7200

The expression that represents the volume of the given cone, in cubic units is 2/3 πx³.
<h3>How to calculate the volume of the cone?</h3>
The volume of a cone with radius 'r' and slant height 'h' is
V = 1/3 π r² h
Unit: cubic units
<h3>Calculation:</h3>
The given cone has radius r = x and height h = 2x
Then, the volume of the cone is calculated by
V = 1/3 π r² h
= 1/3 π x² (2x)
= 2/3 π x³ cubic units
Therefore, the volume of the given cone is V = 2/3 π x³ cubic units.
So, option A is correct.
