11 - 6 = 5
6 - 3 = 3
3 - 2 = 1
Notice how all the differences is an odd number. The number after 11 needs have a difference of 7 when subtracted so it would be B. This sequence is an arithmetic sequence.

stiv31 [10]

Answer:

V = 2304π units³

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = $\frac{4}{3}$ πr³ ( where r is the radius ) , then

V = $\frac{4}{3}$ π × 12³

= $\frac{4}{3}$ π × 1728

= 4π × 576

= 2304π units³

x = 2

5(2 • 2 - 6) + 20

5(2x - 6 )+ 20 = 10

10x - 30 + 20 = 10

10x - 10 = 10

+10 +10

10 / 10x = 20 / 10

x = 2
