f(g(-1)) = - 3
Evaluate g(-1) and substitute into f(x)
g(-1) = (-1)² -7(-1) - 9 = 1 + 7 - 9 = - 1
f(g(-1)) = (-1) - 2 = - 3
Hola!
Circumference of circle is 12.56 cm
Means,
2 × π × r = 12.56
r = 12.56 × 3.14 × 2
r = 1.999 cm
According to Question,
Area of Circle:
π × r²
3.14 × 1.99 × 1.99
12.547 cm² = 12.56 cm² (approximately.)
Hence,
Area of Circle is 12.56 cm²
hope it helps!
