C.
Although this is not the exact answer the circumference formula is 2(pi)r. Which is far more than the other two options.
<span>Information from research studies is sometimes taken out of context. This may happen because the researcher's interpretation of the data is being altered by their own preconceived notions, ideas, beliefs, even cultural values. To correctly interpret data, the researcher must remain completely objective.</span>
X-7=8
Add 7 to both sides so you can isolate the variable
x=15
The power(P) of the circuits is the product of the voltage (V) in volts and current(I) in amperes.
P = IV
Substituting the known values to the equation,
P = (250 amps) x (40 volts) = 10,000 Watts
Thus, the answer is 10,000 Watts.
