Answer:
B
Step-by-step explanation:
The two triangles are congruent because they have three rispective side congruent
AB and AD are both radiuses and AC is in common
so m arc BC is 78 degrees

My understanding is that when the power is a negative number, move it to the denominator and change it to positive.
In this case, the base is y, the power is -3
y^(-3)=1/(y^3)
Answer:
watt is the standard unit of power in metric units
V = πr²h
V = (3.14)(5)²(16)
V = (3.14)(25)(16)
V = 1256
Hope this helps :)
