This is math is easy plz ! points here will give

The exact answer is 27 * pi

or the approximate answer is 27 * 3.14 = 84.78

Step-by-step explanation:

First step is to find the area of the circle

A = pi * r^2

A = pi * 6^2

A = 36* pi

We are missing 90  degrees of the circle  or 90 out of 360.

That means we keep 360 - 90 = 270  or 270/360

The fraction we are keeping simplifies to 3/4  (divide top and bottom by 90)

Multiply the area by the fraction that we kept.

36 pi * 3/4 = 27 * pi

The exact answer is 27 * pi

or the approximate answer is 27 * 3.14 = 84.78
