Plz somebody i need these and i'm failing math cause of these problems.

1.A =113.04  cm^2

2.A =616  in^2

Step-by-step explanation:

To find the area of a circle we use the formula

A = pi * r^2  if we know the radius or

A = pi * (d^2/4) if we know the diameter

In problem 1 we know the radius

A = pi * r^2

A = pi * (6)^2

A = 36*pi

Using 3.14 for pi

A = 36* 3.14

A =113.04  cm^2

In problem 2 we know the diameter

A = pi * d^2/4

A = pi * (28)^2/4

A = pi 784/4

A = 196

Using 22/7 for pi

A = 196*22/7

A =616  in^2

The answer is -1/11 because parrelel means they are the same
