The Area of a circle is 4 pi in^2. What is the circumference, in inches? Express your answer in terms of pi.

Step-by-step explanation:

pi r 2 = 4 pi ^2

then r^2 =4pi

r =2√pi

now circumference of circle = 2pi r

= 2pi 2√pi

= 4 pi √pi

4pi ^2 by √pi

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
