The value 2 / 7 is greater than 4 / 12 is - 1 / 21

<h3>How to perform subtraction in algebra?</h3>

To know the value 2/7 is greater by 4 / 12, we have to subtract 4 / 12 from 2 / 7 .

Therefore,

2 / 7 - 4 / 12 = 24 - 28/84

Therefore,

24 - 28/84 = - 4/ 84 = - 1 / 21

Therefore, it is greater by - 1 / 21

Volume of a Cone Formula: $\displaystyle V = \frac{1}{3} \pi r^2h$

Step-by-step explanation:

Step 1: Define

Radius r = 12

Height h = 71

Step 2: Find Volume

Substitute in variables [Volume of a Cone Formula]: $\displaystyle V = \frac{1}{3} \pi (12)^2(71)$
Evaluate exponents: $\displaystyle V = \frac{1}{3} \pi (144)(71)$
Multiply: $\displaystyle V = \frac{1}{3} \pi (10224)$
Multiply: $\displaystyle V = 3408 \pi$
