Answer:
184.85 square mm
Step-by-step explanation:
The area of a sector of a circle is , where r is the radius and is the angle in radians subtended by the arc at the centre of the circle.
Since, diameter = 40.6 mm
So, radius(r)=20.3 mm and = radians
So, area of sector=
=
Step-by-step explanation:
Answer:
900
Step-by-step explanation:
A=SxS
50265=S^2
S= √50265
S=225
P=Sx4
P=225x4
P=900
Answer:
Its 8.0 I think
Step-by-step explanation:
Hope this helped :)
• Assuming the two horizontal likes are h & l (pic cut off)
• 62 = 6y - 142
• y = 34 degrees
• 180 degrees = straight line
• Because of how things are drawn, 62 + x = 180
• x = 118 degrees
• Check our work: 118 * 2 + 62 * 2 = 360 degrees

➷ a/sinA = c/sinC
Substitute in the values:
37/sin(42) = c/sin(41.5)
Multiply both sides by sin(41.5)
37/sin(42) x sin(41.5) = c
Solve:
c = 36.63999457
The correct answer would be C. 36.64
