Circumference = 2πr = 27 cm
= 2 × 3.14 × r = 27
= 3.14 × r = 27/2
so, r = × = 4.2 cm
Answer:
707.9 cm³
Step-by-step explanation:
What is the volume of a spherical shell with inner radius 7 and outer radius 8?
The formula for the volume of a sphere is given as;
= 4/3 × π × r³
From the above question:
inner radius 7 and outer radius 8
Hence, the volume of a sphere with
inner radius 7 and outer radius 8 is calculated as:
V = (4/3 × π × 8³ ) - (4/3 × π × 7³)
V = 4/3 × π ×(8³- 7³)
V = 4/3 × π × (512 - 343)
V = 4/3 × π × 169
V = 707.9055446 cm³
V = 707.9 cm³
168=n+(n+2)+(n+4)
168=3n +6
168 - 6 = 3n
162/3=n
54=n
integer 1: 54
integer 2=n+2=56
integer 3=n+4=58
Answer:
No, it is not a proportional relationship because the graph does not go through the origin
Step-by-step explanation:
it has to go through zero as in the (origin)
