Area of circle = Pi x r*2
If diameter is 18, radius is 9.
Area = pi (3.14) x r*2 (9*2 = 81) .. 3.14 x 81 = 254.34 sq cen = total area of circle.
A circle is 360 degrees, the shaded area is 270 degrees. the shaded area is 3/4 (270/360) of the area of the circle.
254.34 x 3/4 = 190.755 sq cen
Hope this helps
Sin a * cos b + cos a * sin b=sin (a+b)
sin 78 * cos 42 + cos 78* sin 42=sin (78+42)=sin 120=sin(180-120)=
sin 60=√3 / 2
Answer: sin 78 * cos 42 + cos 78* sin 42=<span>√3 / 2</span>
