Step-by-step explanation:
The formula of a volume of a sphere:

R - radius
We have R = 3 ?. Substitute

If the radius is 30, then the volume is:

If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:

Answer:
35y - 67
Step-by-step explanation:
8(5y - 8) - (5y + 3)
Multiply the 8 with what is in the parentheses.
40y - 64 - 5y + 3
Subtract like terms.
35y - 67
Answer:
Last option.
Step-by-step explanation:
The consecutive exterior angle theorem states that the exterior angles are supplementary if two lines are cut by a transversal.
m∠1 + m∠7 = 180
m∠2 + m∠8 = 180
