A) What is the radius of a circle that has an approximate circumference of 81.64 meters?

1 answer:

8 0

For B, the equation for circumference is pi multiplied by diameter. So, 10 * 2 = 20, and 20*3.14 is 62.8 cm

For C, assuming that "approximate" means that they used 3.14 for pi, then 81.64 / 3.14 = 26, and 26 / 2 = 13 cm

kow [346]

Answer: His answer is wrong

Explanation:

5(1/5^3) = 5(1^3/5^3) = 5(1/125)
5(5^3) = 5(125)

Let’s compare:

5(1/125) < 5(125)

Because 1/125 is smaller 125
Thus, it is not equal.
