4 Find the area of the shape.
Either enter an exact answer in terms of T or use 3.14 for it and enter your answer as a decimal.

The answer is 37.68

We need to find the area of the sector of the circle.

There is a missing part in the upper left part of the circle.

The upper left part central angle measure 90 degree becuase it has a perpendicular sign.

Using central angle and arc theorem, the central angle equal the arc measure so that arc measure is 90 degrees.

There is 360 degrees in a circle so using arc addition,

the rest of the arc measure 270 degrees.

We can use this formula to find the area of the sector

where x is the measure of the central angle and r is the radius.

Plug 270 in for x. The radius is 4.

which is about

37.68

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
