A = 64 pi

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

The radius is 8

A = pi * 8^2

A = 64 pi

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

m∠a is 90°

m∠b is 40°
