Answer:
A ≈ 55.6 cm²
Step-by-step explanation:
The area (A) of the shaded region is calculated as
A = area of circle × fraction of circle
central angle of shaded region = 360° - 230° = 130° , then
A = πr² ×
= π × 7² ×
= 3.14 × 49 ×
≈ 55.6 cm° ( to the nearest tenth )
Answer:
yea
Step-by-step explanation:
Okay, so the y-intercept is the "b" in this case and the m is your slope so, therefore, you have y=- 1/2x-5
The number of sides and number of angles is proportional, for it takes two sides to make an angle. So there are more sides.
Also a cube is not a polygon because a polygon is two dimensional and a cube is 3d.
