I'll do number 11 for you
Area of a sector can be found using
A = (πr²)C/360 where C is the measure of your central angle

A ≈ 23.56 m²
Oh, I guess rounded to the nearest tenth is 23.6
Answer:
+ 3x³ - 3x - 1
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width ) , thus
A = (3x² - 2x - 1)(x² + x + 1)
Each term in the second factor is multiplied by each term in the first factor, then
A = 3x²(x² + x + 1) - 2x(x² + x + 1) - 1(x² + x + 1) ← distribute parenthesis
= 3
+ 3x³ + 3x² - 2
- 2x² - 2x - x² - x - 1 ← collect like terms
=
+ 3x³ - 3x - 1
