Answer:
You are correct.
Step-by-step explanation:
What you do is you add them together which is 2x and it stays in the square root. You are correct.
4 r1 ² π : 4 r2² π = 4 : 9
r1² : r2² = 4 : 9
r1 : r2 = 2 : 3
r2 = 3 r1/2 ( r - radius of the smaller sphere )
10 π = 4/3 r³ π + 4/3 ( 3 r/2 ) ³ π / : π/3
30 = 4 r³ + 4 * 27 r³/8
30 = 4 r³ + 27 r³/2 / * 2
60 = 35 r³
r³ = 60 / 35 = 12/7
V ( Smaller ) = 4/3 r³ π = 4/3 * 12 / 7 π = 16/7 π = 2.286 π cubic units
3v - 18. I hope this helped
Answer:
This is an isosceles right triangle so 45 45 90 degrees because both the opposite and the adjacent are the exact same measure
Thus, Angle E is equal to 45
Answer: 3-sphere
Step-by-step explanation:
In simple terms, geometry is the study of shapes. More specifically, geometry is a branch of mathematics that deals with space, the shapes that inhabit space, and a range of properties that apply to these shapes. ... Geometry also includes topics such as trigonometry – the study of triangles and their properties.
