Find the area of the shaded region. Round to the nearest tenth.

Angle is 150 degrees and side is 6cm.

Area of addition and subtraction.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

the angles measure to 70 degrees, 70 degrees, 20 degrees, and 20 degrees
