Squares : Triangles
3 : 12
Divide both sides by 3.
The simplest ratio is
1 : 4
Step-by-step explanation:
R=2m
A=πr²
A = 3.142*2*2
=12.568 m2
58 * 1,000 = 58,000 its multiplication
45 million *

= 45million * 16 = 720million
Or you can use

A is equal to 45 million
To find the rate, k, we can plug in:




Knowing that t = 4

Given:
The number of seats in the first row is <em>a</em>₁ = 12.
The series of the increasing number of seats is 12, 14, 16......
The objective is to find the total number of seats in the first 12 rows.
Explanation:
The difference between the number of seats in each row can be calculated by the difference between the successive terms of the series.

The number of rows to be calculated is <em>n</em> = 12.
To find the number of seats:
The number of seats presents in the first 12 rows can be calculated as,

On plugging the obtained values in the above equation,

Hence, the total number of seats in the first 12 rows is 276.
