The area of a sector of a circle is $A= \frac{ \theta }{360} * \pi r^2$ . We have everything but the radius to fill in there, so let's do it: $70= \frac{170}{360} * \pi r^2$ . To make it easy, cross out the last 0 in both the 170 and the 360, and then multiply both sides by 36 to get $2520=17 \pi r^2$ . Divide both sides by 17pi and you have 47.1847596=r^2 and r = 6.9
