Answer:

2.4 rad

Step-by-step explanation:

To convert degree measure to radian measure

radian measure = degree measure × $\frac{\pi }{180}$

Thus for 140°

radian = 140 × $\frac{\pi }{180}$ = $\frac{7\pi }{9}$ ≈ 2.4

Answer:

$180\ in.^2$

Step-by-step explanation:

The area of a rectangle can is defined as $A = wl$ where w is the width and l is the length. The width in this case is 12 and the length is 15. Also it doesn't really matter what order you put it in. This gives you an area of $(15\ in.) (12\ in.) = 180\ in.^2$
