Answer:
area of the circle = 3.14 square units
Step-by-step explanation:
Circumference of the circle formula is
where r is the radius of the circle
given circumference = 6.28
= 6.28
Value of pi is 3.14
2*3.14 * r= 6.28
6.28 r = 6.28
divide by 6.28 on both sides
r = 1
radius = 1
Area of the circle =
= 3.14 *1*1 = 3.14

Answer:
f(- 2) = 8
Step-by-step explanation:
Evaluating for x = - 2
f(- 2) = 2 - 4(- 2)³ - 11(- 2)² + 3(- 2) - 6
= (2 × 16) + (- 4 × - 8) + (- 11 × 4) - 6 - 6
= 32 + 32 - 44 - 6 - 6 = 8
