S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)
Answer:
I'm pretty sure that is correct. 3 non collinear points always form a triangle.
Answer:
if two sides and the included angle of one triangle are congruent to two sides and the angle of another triangle, then these two triangles are congruent.
If two triangles share two pairs of corresponding congruent sides are congruent and their included angle is also congruent, then these two triangles are congruent.
If any two sides and angles included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by the SAS rule.
1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 8/8 so 8 laps = 1 miles.
24/8= 3... so that mean he ran 3 miles around the track, to check work:
1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 8/8 so 8 laps = 1 miles.
1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 8/8 so 8 laps = 1 miles.
1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 8/8 so 8 laps = 1 miles.
if you count how many 1/8 there are you'll get 24 '1/8' therefore you know your answer is correct.
