Ответ:
64 pi. Since the formula for the circumference of a cirlcle is: pi x diameter. The diameter of the circle would be 16. And the radius of that would be 8 since its half of 16. The formula to find the area is: pi x radius squared. So 8 squared pi would be 64 pi.
Ответ:
1. k*log(x) = log(x^k)
2. log(x)+log(y)=log(xy)
=>
log_5(11)+2log_5(8)
=log_5(11)+log_5(8^2)
=log_5(11*64)
=log_5(704)
