Answer:
r = the radius, in your case, it's 4 cm. So. Area = π ×r2. = π× (4 cm)2. = 16π cm2 ≈ 50.24 cm2.
Step-by-step explanation:
Answer:
The exterior angle of 60° is 120°. The exterior angle of 65° is 115°. The exterior angle of 55° is 125°.
Step-by-step explanation:
The sum of the interior angle and the exterior angle is 180°. So you can subtract each interior angle from 180 and get the exterior angle.
180° - 60° = 120°
180° - 65° = 115°
180° - 55° = 125°
This is because you can imagine the lines of the triangle extending beyond the triangle. Then you can see where the other angles are. Hope this makes sense!
The answer is 25 because when you count by 5's you would get 25 I'll show you 5 10 15 20 25 I hope this helps you
