Answer:

see explanation

Step-by-step explanation:

- \frac{x}{2} ÷ \frac{5}{7}

• leave the first fraction

• change division to multiplication

• turn the 2nd fraction upside down

= - \frac{x}{2} × \frac{7}{5} ( multiply values on numerators/ denominators )

= - \frac{x(7)}{5(2)}

= - \frac{7x}{10} → B

The area of a circle is 16pi cm2. What is the circle's circumstance?
gavmur [86]
I think you mean circumference...Area is A= \pi  r^{2}. We have the area so we need to use it to solve for the radius which we will then use in the circumference formula.  16 \pi = \pi  r^{2}.  Divide both sides by pi to get \frac{16 \pi }{ \pi } = r^{2}.  Of course the simplification of the left side gives us 16= r^{2} and r = 4.  Now fill that in to the circumference formula, which is C=2 \pi r, to get CC=2 \pi (4) which is a circumference of 8 \pi
