Answer:
The radius of the circle is 3 units. TRUE
The center of the circle lies on the x-axis. TRUE
The center of the circle lies on the y-axis. FALSE
The standard form of the equation is (x – 1)² + y² = 3. FALSE
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9. TRUE
Step-by-step explanation:
x² + y² - 2x - 8 = 0
x² - 2x + y² = 8
Complete the square in x.
x² - 2x + 1 + y² = 9
(x - 1)² + y² = 3²
Center: (1, 0); radius: 3

Hello,
The sum of volumes of the two spheres is
4/3*π*a³+4/3*π*b³=4/3*π*c³
c=∛(a³+b³)=∛(3³+5³)=∛152=5.336803297...≈5.34 (cm)
The diameter of the moon:
25,464(.21)=5,347.44
The radius of the moon:
5,347.44/2= 2,673.72
The volume of the moon:
