Answer:

44.0 cm.

Step-by-step explanation:

The formula for the circumference of a circle is

C=2\pi r

So we can substitute 7 for r and 3.14 for pi:

C=2(3.14)(7)=43.96 cm

And since we're rounding to the nearest tenth, the answer is 44.0 cm.

Inessa05 [86]

Laura paddles in her canoe at a speed of 5 mph for 5 miles.

As we know that

\text{Distance=Speed*Time}\\ \\ Time=\frac{Distance}{Speed} \\

Substitute the values we get

Time=\frac{5m}{5mph}=1hr.......(i)\\

Laura hops on her windsurfer and sails for 12 miles at a speed of 6 mph.

Again using the above formula we can write

Time=\frac{12m}{6mph}=2hr.......(ii)\\

Hence from equation (i) and (ii), we can say total time of travel=1hr+2hr=3hr\\
