Answer:
yes!
Step-by-step explanation:
if it has a 90° angle it is a right triangle :)
C=3.14 x 26
C=81.64
C=2(3.14 x 13)
C=81.64
Answer:
r = 6 m
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
Substitute in what we know
37.68 = 2 * 3.14 * r
37.68 = 6.28 r
Divide each side by 6.28
37.68/6.28 = 6.28 r/6.28
6 = r
