In a conventional gradient, the amount of money in period one is known as the base amount.
<h3>What is an arithmetic gradient? </h3>
An arithmetic gradient series is a cash flow series that either increases or decreases by a constant amount each period.
<h3>What is a base amount?</h3>
Base amount is the fundamental numerical assumption from which something is begun or estimated in a given arithmetic series. It usually occurs in period for a conventional gradient.
Thus, in a conventional gradient, the amount of money in period one is known as the base amount.

Answer:
Area of the circular sidewalk = 405 m²
Step-by-step explanation:
Radius of the circular flower bed = 20 m
Area of the circular bed = πr²
Here r = radius of the circle
Area of the circular bed = π(20)²
= 400π square meter
Radius of the larger circle = Radius of the flower bed + width of the sidewalk
= 20 + 3
= 23 m
Area of the larger circle = π(23)²
= 529π m²
Area of the circular sidewalk = Area of the larger circle - Area of the flower bed
= 529π - 400π
= 129π
= 129(3.14)
= 405.06 square meters
≈ 405 square meters
