How do you find the area of a circle? Isn't it π and something?

Answers

Answer 1

Answer:

Hi there!

You are partially correct on the π symbol, but there's more!

The formula for finding the area of a circle is:

A = π r².

A stands for area, π stands for pi, and r stands for radius. The ² is there because the radius is half as big as the diameter of a circle.

Hope this helps! :D

And remember, you can message me whenever you need to on anything you may need help with!

jasmines cd collection is 3/8 jazz 1/4 rap and the rest is rock music what is the fraction of rock music

Answers

rap - 1/4
jazz - 3/8
rock - x
all - 1

jazz + rap + rock = all

3/8 + 1/4 + x = 1
3/8 + 2/8 + x = 1
5/8 + x = 1
x = 1 - 5/8
x = 3/8

answer: rock - 3/8

$a- all\n j-jazz\n r_a-rap\n r_c-rock\n\n a=j+r_a+r_c\Rightarrow r_c=a-j-r_a\n\n r_c=1-(3)/(8)-(1)/(4)\n\n r_c=1-(3)/(8)-(2)/(8)\n\n r_c=(8)/(8)-(3)/(8)-(2)/(8)\n\n r_c=(3)/(8)$

Find the difference between 400 and 273

Answers

To find the difference between,

$400$
and
$273$
means what number should we add to 273 to obtain 400.

To find that number, we subtract 273 from 400.

To do that we need to set up the numbers as below to make the calculation easy for us.

$\: \: \: \: \: \: \: \: 10 \n \: \: \: \: 39 \n \: \: \: \: 400 \n ( - 273)/( \: \: \: \: 127)$

We do the subtraction from right to left.

The first digits are 0 and 3. Since 0 is less than 3, we 'borrow' from the next digit.

But sad for us, the next digit to the right is also zero. So we borrow from the from the first non-zero digit which is 4.

Borrowing 1 from 4 makes the hundred digit reduce to 3. Since we are operating in base 10, the 1 we borrow has a value of 10. Adding that 10 to the zero at the immediate right of 4 makes it 10. Now we can borrow one from this "10". That makes it become 9. That is why you are seeing '39' at the top of the '40'. Now our right mist zero has a value of 10(written at the topmost right).

We subtract 3 from 10 now to get 7.

Then 7 from 9 to get 2.

and 2 from 3 to get 1.

Hence

The difference between,
400 and 273 is 127.

The difference between 400 and 273 is 127

The given numbers are,

400 and 273

The difference between 400 and 273 is calculated by subtracting the smaller number from the larger number. So,

400 - 273 = 127.

Now take a creative approach to solve it,

Imagine you have a basket of 400 apples, and a friend takes away 273 apples. How many apples do you have left?

Simply subtract:

400 - 273 = 127.

Or simply

4 0 0

- 2 7 3

__________

1 2 7

___________

So, the difference between 400 and 273 is 127 apples.
