Formula for the area of a circle:

A = πr²       (A = area     π(pi) = 3.14.......      r = radius)

You know:

r = 9.5 cm      and you're using 3.14 for π, so substitute/plug it into the equation

A = πr²

A = (3.14)(9.5)²     Find 9.5²

A = (3.14)(90.25)

A = 283.385 cm²

I’m just typing here but I uploaded a picture of my work. I got 283.385 cm
