Norah knows that the diameter of a circle is 13 meters how would you tell her to find the circumference​

answer: 414,377,008

step-by-step explanation:

just multiply it

ratio is 2 : 9

the answer is three

13.5 : 3

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

your answer is

a.
