Find the circumference of a circle if the diameter is 24 feet.

~75.4 ft

Step-by-step explanation:

C = 2*pi*r = pi*d = pi*24 = ~75.4 ft

C: circumference

r: radius

d: diameter

pi = ~3.14

24π ft

Step-by-step explanation: To find the circumference of a circle with a diameter of 24 feet, start with the formula c = πd.

Now we can plug the diameter into our formula.

So we have (π)(24 ft) which is equal to 24π ft.

So the area of the circle is 24π ft.

So the number of total combinations is 24+30=54.

Step-by-step explanation:

We know that Peg has 4 long-sleeve shirts, 5 short-sleeve shirts, and 6 pairs of pants. We assume that she is going to wear a shirt and a pair of pants.

First, we calculate the number of combinations for a pants and long-sleeve shirts. She have 6 pairs of pants and 4 long-sleeve shirts.  

We get: 6 · 4 = 24

Now, we calculate the number of combinations for a pants and  short-sleeve shirts. She have 6 pairs of pants and 5 short-sleeve shirts.  

We get: 6 · 5 = 30

So the number of total combinations is 24+30=54.
