In a circle, where centred is 0, and with a sector and the major and minor arcs indicated.
Major arc is 40cm.
The length of the
corresponding major arc, FE, is 40 cm.
What is the circumference of the circle, in
cm?
(A) 24
(B) 48
(C) 50
(D) 64​

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

answer: b.36 feet
