1 answer:

4 0

Circumference = 2 $\pi$ r

Solve for r.

2 $\pi$ r = 37.7
Divide both sides by 2.

$\pi$ r = 18.85
Divide both sides by $\pi$ .

r = 6

The radius is 6 cm.

What is 9-x/5=3?<br> I kept getting 6 but the only option is -6 :/

borishaifa [10]

Step-by-step explanation:

$9 - \frac{x}{5} = 3 \\ 9 - 5 \times \frac{x}{5} = 3 \times 5 \\ 9 - x = 15 \\ - 9 - x = - 9 + 15 \\ - x = 6 \\ - x \div - 1 = 6 \div - 1 \\ x = - 6$
