Answer:
Area = 49π
Step-by-step explanation:
circle Area = π x (radius)²
Assuming d = 14 is the diameter (which the problem really should state explicitly, not leave you to assume), then the radius is half of that.
So r = 7, where 'r' is the radius.
Area = π x r² = π(7)² = π(49)
Area = 49π is the exact answer, so it is the one I prefer.
Area = 153.86 is the decimal you get if you multiply 49 x 3.14
Hope this helps.

my answer would be c. y=lX+7l
Answer:
82
Step-by-step explanation:
f(x) = 5x - 3
g(x) = 2x + 9
f(g(x)) = 5 (2x + 9) - 3 ..... replace x with g(x)
f(g(4)) = 5 * (2 * 4 + 9) -3 = 85 - 3 = 82
Answer: yeah jadhdkdkdkdje
Supplementay means adds to 180
x and y could be 100 and 80
x and y could be 1 and 179
acute means that it is less than 90
since we are not told what x or y is, y could or could not be acute
