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:
Katrina got 86 in her test
Step-by-step explanation:
given
mean = 80
standard deviation = 3
z-score = 2
Let score of Katrina = x
Recall z-score is calculated by
z-score = (x-mean) / standard deviation
substitute values and solve for x
2 = (x-80)/3
x-80=6
x = 86
Answer:
x = 36
Step-by-step explanation:
the supplementary angle in the lower right corner is 180 - 150 = 30°.
sin 30 = 18/x
0.5 = 18/x
x = 36
Yes,you got the correct answer!
To prove x≥-32:
Therefore x≥32.
