The circumference of a circle is 5 pi cm. what is the area of the circle?

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
