Find the area of a circle with a circumference of 11 feet

94.985 feet

Step-by-step explanation:

the formula for area of a circle is pi×r²

if you are using 3.14, it is 94.985

if you are using pi, then it is 95.03317777

step-by-step explanation:

compare

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.
