What is the approximate circumference of a circle with a radius of 30 inches? Use π ≈ 3.14.

1 answer:

3 0

The circumference of a circle is the distance around the circle. The circumference of a circle is calculated by the expression:

Circumference = 2πr

Circumference = 2π(30 inches)
Circumference = 94.2 inches

Therefore, the correct answer from the choices listed above is option C. Hope this answers the question.

Answer:

Option B

Step-by-step explanation:

We can see that, from the picture provided, the graphs intersect at points( 0, 4 ) and ( - 4, 4 ), respective to functions f( x ) and g( x ). These intersection points makes each function equivalent to one another, and hence -

Function f( x ) where x = - 4 / Function g( x ) where x = - 4,

$f( - 4 ) = 4,\\g( - 4 ) = 4\\----------\\f ( - 4 ) = g ( - 4 )$

Respectively function f( x ) where x = 0 / Function g( x ) where x = 0,

$f( 0 ) = 4,\\g( 0 ) = 4\\----------\\f ( 0 ) = g ( 0 )$

Your solution should be option b, " f(-4) = g(-4) and f(0) = g(0) "

Step-by-step explanation:

The related function is reflected across the x-axis and translated up 3 units. Effectively, it is reflected across the line y = 3/2. The graph of the related function is shown in blue in the attachment.
