Every school kid has been told that a circle of radius r has circumference=2\[pi] r. here is a parameterization of a circle of radius r: clear[x, y,t, r]; {x[t_],y[t_]}={r cos[t],r sin[t]}{r cos[t],r sin[t]}to get the whole circle, you run t from 0 to 2\[pi].use this information to confirm that the circumference of a circle of radius r measures out to 2\[pi] r units long.

the monthly balance will be $75,000

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.

other answer is correct. i had used the radius of the radius somehow. a website:
