The diameter of a circle is 12 inches. What is the area of the circle. Use 3.14 for the radius

R=6

A=36 Or 113.09733552923(113.1 rounded to the nearest tenth)

Step-by-step explanation:

R=d/2

12/2=6

A=

12/2=

6*6=36

(36*3.14=113.09733552923 if you don’t have pi symbol)

113.09733552923 rounded=113.1

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.
