The greatest common factor of 64 and 96 is... uhh... hmm... 32! Because 64/32 is 2, and 96/32=3. 2 and 3 have no factors in common, except 1.
The answer is 32(2+3).
This means 32*2 + 32*3
this is the same as 64+96

The radius of a circle measures 15 ft. What is the circumference of the circle?

Pie

Answer:

$\boxed {\tt 94.2 \ feet}$

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

$c= \pi d$

where d is the diameter. We are given the radius, so let's find the diameter.

The diameter is twice the radius.

$d=2r$

The radius is 15 feet.

$d= 2 * 15 \ ft$

Multiply.

$d= 30 \ ft$

Now we know the diameter. Substitute 30 feet in for d.

$c= \pi d$

$c=\pi * 30 \ ft$

We are using 3.14 for pi, so substitute it in.

$c=3.14 * 30 \ ft$

Multiply.

$c= 94.2 \ ft$

The circumference of the circle is 94.2 feet.
