Is circumference cubed, squared, or just left alone?

Circumference is a linear distance. So if the diameter is in feet, then the circumference is also in feet (not square feet or cubic feet)

-------------------------------------

Example:

Let's say we had a circle with diameter d = 10 feet

The circumference is approximately...

C = pi*d

C = 3.14*10

C = 31.4

The circumference is roughly 31.4 feet

The circumference is essentially the distance around the circle's edge. We can use a flexible ruler or a string to help measure out this distance, or you can imagine laying the circle's edge to be placed along a straight line, which is another way to help measure the perimeter.

1). 21 is what percent of 168. 4) what number is 62 percent of 50

malfutka [58]

1) 21 is 12.50% of 168.

2) 4% of 150 is 6.

3) 1% of 500 is 5.

4) 62% of 50 is 31.

5) 15% of 15 is 2.25

6) 40 percent of 25 is 10.

Step-by-step explanation:

1). 21 is what percent of 168.

Let,

x be the percent.

Therefore,

x% of 168 = 21

$\frac{x}{100}*168=21$

$1.68x=21$

Dividing both sides by 1.68

$\frac{1.68x}{1.68}=\frac{21}{1.68}\\x=12.50$

21 is 12.50% of 168.

2). What is 4 percent of 150.

4% of 150 = $\frac{4}{100}*150$

4% of 150 = $\frac{600}{100} = 6$

4% of 150 is 6.

3) 1 percent of 500 is what number

1% of 500 = $\frac{1}{100}*500$

1% of 500 is 5.

4) what number is 62 percent of 50

62% of 50 = $\frac{62}{100}*50$

62% of 50 = $0.62*50=31$

62% of 50 is 31.

5) 15 percent of 15 is what

15% of 15 = $\frac{15}{100}*15$

15% of 15 = $\frac{225}{100}=2.25$

15% of 15 is 2.25

6) 40 percent of 25 is what number

40% of 25 = $\frac{40}{100}*25$

40% of 25 = $\frac{1000}{100}=10$

40 percent of 25 is 10.
