Answer:

Step-by-step explanation:

Circumference = 37.68 units

2πr = 37.68

2*3.14*r = 37.68

$r=\frac{37.68}{2*3.14}\\\\$

r = 6 units

Area =πr²

= 3.14*6.6

= 113.04 square units

Answer:

112.98 square units

Step-by-step explanation:

Let's work backwards:

Circumference = 2πr

(37.68)/2π = r

Area = π $r^{2}$

Area = π * $((37.68)/2pi)^{2}$

Area = 112.983 square units

First one.

Since the two angles are congruent through vertical angles theorem,

5x = 6x - 8

5x - 6x = -8

-x = -8

x = 8

Second one.

Use the 180° rule.

(8x - 2) + (2x + 2) = 180

8x - 2 + 2x + 2 = 180

8x + 2x + 2 - 2 = 180

10x = 180

x = 180 / 10

x = 18

Third one.

Vertical angle theorem.

7x = 5x + 40

7x - 5x = 40

2x = 40

x = 40 / 2

x = 20
