Acircle has an area of 49 pi^3. what is the radius of the circle?

radius = 7π

Step-by-step explanation:

The area (A) of a circle = πr² ← r is the radius

The area is given as 49π³ , equating gives

πr² = 49π³ ← divide both sides by π

r² = 49π² ← take the square root of both sides )

r = = 7π

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
