What is the area of a circle with a diameter of 28 inches? Answer in terms of Pi. *
5 points

28 cm

14 cm

7 cm

196 cm

Formula for the area of a circle:

A = πr²         (A = Area         π(pi)          r = radius)

You know:

r = 14 inches          So substitute/plug it into the equation

[Radius is (half) of the diameter. The diameter is 28, so half of 28 = 14]

A = πr²       Plug in 14 into "r" since r = 14

A = π(14)²      Find 14²  -->  14 x 14 = 196

A = 196π in²        Your answer is the 4th option

(-5,-28)
