Answer 1

@makayla_finkbeiner_

Answer 2

\[A=πr ^{2}\]

Answer 3

Can you try by yourself first?

Answer 4

does that mean i do 3.14*8

Answer 5

Do you know what the radius is?

Answer 6

is the radis 3.14

Answer 7

The line on the circle goes through the whole thing. This means that line is the diameter. The radius is half the diameter, so the radius is 4.

And, no. pi is 3.14

Answer 8

Do you know how to square a number? Like:\[4^{2}\]

Answer 9

So then its 16 ^ his square because you multiply the 4 2 times so 4x4=16

Answer 10

Squaring a number is multiplying it by itself. So, \[4^{2}=16\]

Answer 11

ok

Answer 12

So, the equation comes out to: \[3*16\]The reason I took of the 0.14 is because they want an estimate of the answer.

Answer 13

So, type into your calculator, 3*16

Answer 14

i got 48 for 3*16

Answer 15

Yes, that's the answer.

Answer 16

Very good :)

Answer 17

thanxs guys im trying to get use to this before theFCAT

Answer 18

Remember...
Step 1: find radius, which is half of the diameter
Step 2: Square that number
Step 3: Multiply that number by the 3.14, but in this case they are asking you to estimate, so you drop the .14 because you are suing round numbers
FCAT is extremely easy, you will do great I promise Ive taken it for 5 years now and never failed, good luck
