Find the circumference and area of a circle with a diameter of 14 inches. Leave your answers in terms of pi. A.) C = 14π; A = 49π B.) C = 7π; A = 28π C.) C = 14π; A = 28π D.) C = 7π; A = 49π

c please tell if I was right

A)   C = 14π and A = 49π

Step-by-step explanation:

Circle dia (d) = 14 in

radius (r) = 14 / 2 = 7in

find: area and circumference

Area = π d² /4

Circumference = 2 π r

1) Area = π (14²) / 4

  A = 49π

2) Circumference = 2 π (7)

     C = 14π

therefore, the answer is A) C=14π and A=49π

$12. that is my answer.

answer is c

step-by-step explanation:

81/12=324/x

x=48
