A circle with center at (-2,2) passes through (7,2). Find the circumference and area of the circle in terms of p.

18pi units is the circumference

81pi units² is the area

Step-by-step explanation:

Radius² = (-2-7)² + (2-2)² = 9²

Radius = 9

Circumference = 2pi×r

= 18pi

Area = pi × r²

= 81pi

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.
