Answer:
1,203,650,000 mi³
Step-by-step explanation:
Volume of a sphere is given by V = (4/3)πr³
in this case diameter D, = 1320 mi
radius, r = D/2 = 1320 / 2 = 660 mi
volume V, = (4/3)(3.14) (660)³
= 1,203,649,920 mi³
= 1,203,650,000 mi³ (nearest thousand)
Answer:
<u> We can conclude that Δ XYZ ≅ Δ RST by ASA postulate.</u>
Step-by-step explanation:
Δ XYZ and Δ RST are congruents by ASA postulate because:
1. Their included sides XZ and RT are equal.
2. Their angles ∠Z and ∠T are equal (92° = 92°)
3. Their angles ∠X and ∠R are equal.
4. Their non-included sides XY and RS are equal.
<u>Now, we can conclude that Δ XYZ ≅ Δ RST by ASA postulate.</u>
Step-by-step explanation:
Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.
52 = ½ (x − 38)
x = 142
Arc angles add up to 360.
360 = 80 + 38 + z + x
z = 100
Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.
y = x/2
y = 71
