If the area of a circle is 31.36pi, then what is its radius?

1 answer:

4 0

You would:

31.36 divided by pi and that will give you r2
you would then need to divide r2 by 2 to get the radius and there is your answer
I got:
9.982 for the first part
then 9.982 divided by 2= 4.991 for my final answer
I hope this helps

What are the values of x and y if this equation is true? 22(x + yi) + (28 + 4i) 72 – 62i

ASHA 777 [7]

Answer:

x = 2

y = -3

Step-by-step explanation:

The given equation is,

22(x + yi) + (28 + 4i) = 72 - 62i

By solving this equation further,

22x + 22yi + 28 + 4i = 72 - 62i

(22x + 28) + (22y + 4)i = 72 - 62i

Now both the sides of the equation is in the form of complex number,

By comparing real and imaginary parts given on both the sides,

22x + 28 = 72

22x = 72 - 28

22x = 44

x = 2

22y + 4 = -62

22y = -62 - 4

22y = -66

y = -3

Therefore, x = 2 and y = -3 are the values for which the given equation is true.

Based on the Egyptian Social Pyramid, which statement below is true?

Novosadov [1.4K]

Answer:

Third Option

Step-by-step explanation:

Lets use process of elimination to find the answer to this question. It's not the first option because a scribes job was mainly in the government district as writers/record keepers meaning they don't really protect the kingdom from invasion. It's not the second options because Merchants were traders, meaning they don't make up the Pharaohs police force because all they do is sell goods to Egyptians. Then it's not fourth option because farmers, servants, and slaves make up way more then 20% of ancient Egypt. Leaving the third option meaning it's your answer.

Hope this helps.
