Answer:
900
Step-by-step explanation:
(n – 2)180 where n is the number of sides
since this is a 7 sided polygon
(7-2) * 180
5 * 180
900
I’m pretty sure the answer is 127.48 ,but I could be wrong.
Answer:
41.29 cm²
Step-by-step explanation:
From the question,
Area of the shaded portion = Area of the circle - area of the square.
A' = πr²-L²...… Equation 1
Where A' = Area of the shade portion, r = radius of the circle, L = length of the square, π = pie
Given: r = 4 cm, L = 3 cm
Constant: π = 22/7.
Substitute these values into equation 1
A' = [(22/7)×4²]-3²
A' = 50.29-9
A' = 41.29 cm²
Hence the area of the shaded portion is 41.29 cm²

Undefined slopes are when x equals a certain number.
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
From the given choices, B is the correct answer.
A has a slope of 0, so <em>m</em> = 0 and would become a horizontal line.
C has a negative slope, so it is not undefined.
D has a positive slope, so it is not undefined.
B shows a vertical line, and so it has an undefined slope.
