Find the circumference and area of a circle with a diameter of 22 inches. Leave your answers in terms of pi. (4
points)
C = 117T; A = 4411
C = 22T; A = 44TT
C = 111; A = 1211
C = 2211; A = 1211

  C = 22π; A = 121π

Step-by-step explanation:

The relevant formulas for circumference (C) and area (A) are ...

  C = πd . . . . . d is the diameter

  A = πr² . . . . where r = d/2

Filling in the given value for diameter, we have ...

  C = 22π

  A = π(22/2)² = 121π

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

$6.42
