Brad will put fencing around a circular area in his yard for some baby goats he purchased. If the circular area will have a radius of 10 feet, how many feet of fencing will Brad need?​

Ineed asap. 35 points. in order for two polygons to be similar, two conditions must be met. first, all pairs of corresponding sides must be in proportion. second, all corresponding angles must be congruent. prove that angle congruence is not enough, by itself, to establish that two polygons are similar. do this by describing or drawing two polygons that are not similar but whose corresponding angles are all congruent.
