Can yall like help !

1486

Step-by-step explanation:

(60 x 60)/2=1800- area of triangle

A=Pi r ^2

A= 3.14 x 10^2

A=3.14 x 100

A= 314

1800-314= 1486

1,486 square meters

Step-by-step explanation:

First, you need to figure out the area of the triangle using the formula 1/2bh.

1/2 (60)(60) = 1800

Next, you need to find the area of the circle using the formula πr². The question instructs you to use 3.14 in place of π. The diameter is 20, meaning the radius is 10.

(3.14)(10)² = 314.16

Now all you have to do is subtract the two values because you are trying to find the shaded region within the triangle.

1800 - 314.16 = approximately 1,486

if you was gonna solve for a, a is a   < -12
