A.12.56 mm
B.25.12 mm
C.50.24 mm
D.502.4 mm

Answer 1

Ok the formula for area of circle is

\[A=\pi \ r ^{2}\]

when you plug it in what do you get @Ashsmashum1290

Answer 2

12.56?

Answer 3

4

Answer 4

Good now what did you do wrong with 12.56 answer?

Answer 5

i did 3.14x4

Answer 6

you forgetting something @Ashsmashum1290 look at the formula again
\[A=\pi \ r ^{2}\]

Answer 7

dont forget the r^2 thats a common mistake made by people but costly. Thats why they put a distractor in the answer choices that looks like the answer but is not.

Answer 8

what do i do divide?

Answer 9

No remeber when you square something you *Multiply* it so if its 12^2 that means its 12 times 12 which is 144 or 5^2=25 you get it? @Ashsmashum1290

Answer 10

so if 4^2 what is it?

Answer 11

8

Answer 12

Thats 4*2 i mean 4 square remember what i said above. If it was 12 times 2 it would of been 24 but its 12 square which is 144.

In other words its like 4*4 or 12*12 or 15*15

Answer 13

theres square and cubed. Cubed is by 3.
so if its 12^3 or cubed it is 1728

Answer 14

Lets try one more time. You got this :D

4^2=? @Ashsmashum1290

Answer 15

what is that sign in the middle of the 4 and 2?????

Answer 16

\[4^{2}=?\]

Answer 17

4x2=8

Answer 18

Answer 20

Please read it

Answer 21

okay i read it but i still don't get it :(

Answer 22

ok you know how 4*2=8 right? so for this it squared which is like saying the number multiplied by its self so for example

5*2=10 but \[5^{2}=25\]

Answer 23

16?

Answer 24

Correct so if you plug it in what do you get

\[A=\pi \ 4^{2}\]

Answer 25

plug in the 3.14?

Answer 26

yea :D

Answer 27

50.24

Answer 28

the \[\pi \ is \ the \ 3.14\]

Answer 29
