Answer:
x = (2600/4000) × 100%
x = 0.65 × 100%
x = 65%
Step-by-step explanation:
The percentage equation that can be used to find the percent of books that are fiction can only be found where the number of fiction books is known and the total number of books available is known as well.
Given;
Number of fiction books = 2,600
Number of books = 4,000
let the percent of books that are fiction be x
x = (2600/4000) × 100%
x = 0.65 × 100%
x = 65%
Answer:
C.
Step-by-step explanation:
Area of a Sector Formula: A = x/360πr²
Since we are given <em>x</em> and <em>r</em>, simply plug it in:
A = 40/360π(4)²
A = 1/9π(16)
A = 16π/9
