Answer:
1) 40°
2) 140°
3) 140°
5)40°
6)140°
7)140°
8)40°
Step-by-step explanation:
1 = 40 ° <em> [Vertically Opposite angles are equal]</em>
8 = 40 ° <em>[Corresponding Angles are equal]</em>
5 = 8 = 40° <em> [Corresponding Angles are equal]</em>
7 = 180° - 40° = 140° <em>[Supplementary angles sum 180°]</em>
6 = 140° <em> [Vertically Opposite angles are equal]</em>
2 = 140° <em>[Corresponding Angles are equal]</em>
3 = 140 ° <em> [Vertically Opposite angles are equal]</em>
Answer:
Step-by-step explanation:
The surface area of a cylinder is the area of the bases plus the area of the side, or SA = 2*A₁ + A₂
Since the area of a circle is
,
SA = 2*() + A₂
Since the area of the side is height * the circumference of the circle or A₂ = h *
, then SA must be;
SA =
SA =
SA =
SA ≈ <span>351.858377202</span>
Since the area of a circle is
SA = 2*(
Since the area of the side is height * the circumference of the circle or A₂ = h *
SA =
SA =
SA =
SA ≈ <span>351.858377202</span>
