what is the area of a circle if its radius is 3596cm let pi=3.14

Answers

Answer 1
Answer: Area of a circle of radius r : A=\pi r^2

3596cm = 35.96 m hence

Hence here A=\pi r^2\approx3.14\cdot(35.96)^2=3.14\cdot1293.1216=4,060.401824m^2

Answer:Answer:

C. 120°

Step-by-step explanation:

m∠d = 150°

m∠ a = 90°

The sum of angles at a point add up to 360°

m∠b + m∠c +m∠e = 360° - (90° + 150°) = 120°

Uhh, well a rate is a special ratio in which the two terms are in different units and a ratio is a comparison between two numbers or measurement. So I guess it's never true!

Is 45/5 equal to a whole number or a mixed number?Please Explain How You know

Answers

Answer:

(45)/(5) is a whole number.

Step-by-step explanation:

Given : A fraction (45)/(5)

We have to determine whether the given fraction (45)/(5) equal to a whole number or a mixed number.

Whole numbers are those numbers that do not involves fractions.Example : 1, -10 , etc

Mixed numbers are numbers that are combination of an integers and a proper fraction. Example 1(1)/(4),2(1)/(9) etc.

Consider the given fraction (45)/(5)

45 can be written as product of 9 and 5

Thus, fraction becomes,

(45)/(5)=(9* 5)/(5)  

On simplifying, we get (45)/(5)=9

Thus, 9 is an intger with no fraction.

Hence, (45)/(5) is a whole number.
Yes it is. Because if you simplify the fraction 45/5, you will get 9/1 which is the same as 9, which is a whole number.

66 is what percent of 120?

Answers

               120 = 100%
                 66 =  x %

120x = 6600
     x = 6600
            120
     x = 55

S = 55%
You would create a proportion ... so since percent is out of 100, you would do 66/120 = x/100. Then you would cross multiply, solving 66x100 (which equals 6000). The final step is to divide that product by the leftover number, which is 120. So you basically would do 6600/120 to get the answer.
