ANSWER

EXPLANATION
The circumference of a circle is calculated using the formula:

where r=11 meters is the radius of the circle.
Let us substitute the radius into the formula to obtain,

This simplifies to:

When we substitute

We get

to the nearest hundredth.

4 + 3 = 7 (add exponents because its multiplication)
Answer:
Step-by-step explanation:
Recall that we say that d | a if there exists an integer k for which a = dk. So, let d = gcd(a,b) and let x, y be integers. Let t = ax+by.
We know that
so there exists integers k,m such that a = kd and b = md. Then,
. Recall that since k, x, m, y are integers, then (kx+my) is also an integer. This proves that d | t.
