Answer:

The circumference of the circle is about <u>166.42 </u>cm.

The area of the circle is about <u>2205.07 </u>cm².

Step-by-step explanation:

Diameter = 53 cm

Radius = r = 53cm/2 = 26.5 cm

π = 3.14

Circumference = C = 2 π r

C = 2(3.14)(26.5cm) = 166.42cm

The circumference of the circle is about 166.42cm.

Area = A = π r²

A = (3.14)(26.5cm)² = 2205.07 cm²

The area of the circle is about 2205.07 cm².

3.) SOLVE FOR X.
gayaneshka [121]

The value of x in the secants intersection is 1 units

The value of NM in the tangent and secant intersection is 51 units

<h3>How to find length when secant and tangent intersect?</h3>

The first question, two secant intersect outside the circle.

Therefore,

(6x + 8x)8x = (9 + 7)7

14x(8x) = 16(7)

112x² = 112

x² = 112 / 112

x = √1

x = 1

The second question, tangent and secant intersect,

Therefore,

(x + 3)² = (x - 3)(16 + x - 3)

(x + 3)² = (x - 3)(x + 13)

(x + 3)(x + 3) = (x - 3)(x + 13)

x² + 3x + 3x + 9 = x² + 13x - 3x - 39

x² + 9x + 9 = x² + 10x - 39

x² - x² + 9x - 10x = -39 - 9

-x = - 48

x = 48

NM = 48 + 3 = 51 units
