4+3(7+4 x 2)-100
4+3(7+8)-100
4+3(15)-100
4+45-100=
-51
I assume the answer is 1/4
Split the shape in 3 rectangles
4x2=8x2= 16 ( the bottom and top rectangle)
6x2= 12 (middle rectangle)
16+12=28
There are 2 ways of measuring angle. It is either by radians or by degree. Radians is unitless or we just call it rad. A pi is equivalent to 180 degrees. A pi is equal to 3.14. So when we answer this we multiply 216 by pi/180 or 2pi/360. The answer is 3.7699 or 3.8 rad.
