For this case we have the data of a base and a height given by:

$b = 1\ ft\\h = 6\ in$

We convert the inches to feet.

We know that, by definition:

1 foot equals 12 inches

By making a rule of three we have:

1 ft ------------> 12 in

x ---------------> 6 in

$x = \frac {6 * 1} {12}\\x = \frac {6} {12}\\x = \frac {1} {2}\\x = 0.5 \ ft$

If the given figure is a rectangle, the area is given by:

$A = b * h\\A = 1 * 0.5\\A = 0.5\ ft ^ 2$

If the given figure is a rectangle, the area is given by $A = 0.5\ ft ^ 2$

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 = $\sqrt{49(\pi )^2}$ = 7π
