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

idk

step-by-step explanation:

i don't know

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
