Help please find the circumference of the circle

10 i believe

Step-by-step explanation:

C = 5pi inches or approximately 15.7 inches

Step-by-step explanation:

The circumference of a circle is given by

C = pi *d

The diameter is given by d=5

C = pi *5

If we use pi is approximated by 3.14

C = 3.14 *5 =15.7

C = 5pi inches or approximately 15.7 inches

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.
