Question

Help me please.

Answer 1

Questions here.

Answer 2

i know there's a formula you can use, but i can't remember what is is :(

Answer 3

Here is the formula:
\[A=\frac{ n }{ 360 }\pi r^2\]

Answer 4

Ok so what do i do next?

Answer 5

Plug in the values for n and r
n is the degrees
r is the radius
\[A=\frac{ 100 }{ 360}\pi(7)^2\]

Answer 6

Ok and how do i plug it in.

Answer 7

It is plugged in in the comment above

Answer 8

the radius is 7
the degrees is 100

Answer 9

Well how do i plug it easier into a calculator ?

Answer 10

You can simplify the exponent in \[7^2 \to 49\]

Answer 11

So now you should have\[A=\frac{ 100 }{ 360 }\pi(49)\]

Answer 12

To simplify the fraction you can divide both the numerator and denominator by 10 to get\[A=\frac{ 10 }{ 36 }\pi(49)\]

Answer 13

Ok thanks ill do that now :)

Answer 18

Lets do this step by step. \[\frac{ 10 }{ 36}(49)=?\]

Answer 19

10/36/(49)=0.13611111111

Answer 20

The only thing wrong with you ranswer here is the placement of the decimal. The decimal should be after the first 3.
Now lets do the next step:\[13.61111111\pi=?\]

Answer 21

How would i put that in a calculator?

Answer 25

You would put it just like mentioned above 13. whatever * pi

Answer 26

42.7388888885????

Answer 28

Yep

Answer 29

thats the answer?

Answer 30

@TheCalcHater

Answer 31

You might want to get some practice using your calculator. Plugging things into one is meant to be easy.

Answer 32

Can u help me then?

Answer 33

\[A=\frac{ 100 }{ 360 }\pi(7^2)\]if you can read this, you can enter it into a calculator.

You'd enter 100/360*pi*7^2

I can't help you plug it into a calculator any more than that.

Answer 34

ok i got 100/360*pi*7^2=42.7605666739

Answer 35

Yep.

Answer 36

That the answer?

Answer 37

You seem to have trouble understanding the meaning of the word "Yep"
