Hello, I Am BrotherEye
Answer:
27.92 units
Step-by-step explanation:
Radius (qr) = r = 16 units
<QŘS = θ = 82°
Length of an arc = (Θ / 360) * 2πr
L = (θ / 360) *2πr
L = (82 / 360) * 2π * 16
L = 0.2777 * 100.53
L = 27.917 units
L = 27.92 unit
Best Of Luck

Answer:
Area = w x (5+ 8 w)
Step-by-step explanation:
Recall the formula for the area of a rectangle: Area=with x length
You are suggested to use "w" to represent the width of the pen.
Now, they give you information about the length of the pen in word form.
We are converting those words into an algebraic expression:
"The length of the pen is 5 more than 8 times the width of the pen"
Length = 5 + 8 w
So we replace the length of the pen with this expression in the area formula:
Area = w x (5+ 8 w)
Answer:
a² + 4ab + 4b²
Step-by-step explanation:
Given
(a + 2b)²
= (a + 2b)(a + 2b)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis
= a² + 2ab + 2ab + 4b² ← collect like terms
= a² + 4ab + 4b²
Okay so write it like this 27.50 thats the answer
