Answer:
Area is = to 1017.88
Circumference is = to 113.1
Step-by-step explanation:
To find the area of a circle use the formula A=πr2
So . . .
A = π18²
A = π324
A = 1017.88
To find the circumfrence of a circle use formula C=2πr
So . . .
C = 2π18
C= 113.1

Answer:
The value of number is 82.5
Step-by-step explanation:
Given as :
Let The number = x
∴ 25.6 % of x = 21.12
Or, 25.6 × x = 21.12 × 100
Or, 25.6 × x = 2112
∴ x = 
i.e x = 82.5
Hence 25.6 % of 82.5 is 21.12 So , The value of number is 82.5 Answer
Answer:
Angle Bisector.
Step-by-step explanation:
Okay.
SU is the line across the triangle.
It isn't perpendicular because it will meet the lines eventually.
Median is a number.
I believe It's the Angle Bisector, but i'm going off of a gut feeling.
Length of the rectangular acting area be x.Width = 42 / xWe asked to find the perimeter ( the number of yard that are needed to enclose the area)P = 2(length + width) = 2(x + 42/x) = 2x + 84/x
The perimeter is minimum when the differentiation is equal to 0.2 - 84/x^2 = 02x^2 - 84 = 0x^2 = 42 x = 6.48
Thus, the minimum yards of string lights the manager need to enclose the area is 2(6.48) + 84 / 6.48^2 = 12.96 + 12.96 = 25.92 so it is approximately 26 yards
