Answer 1

It's the area of the entire circle, minus the hole in the middle.

Answer 2

how do i find the area of the entire circle? @doc.brown

Answer 3

well look at the diagram, what is the radius of the inner circle..?

and what is the radius of the outer circle...?

Answer 4

2.2 is the outter and 5.4 inner

Answer 5

nope... 5.4 is a diameter of the inner circle... whats the radius...

then when you get that, add 2.2 to it to get the radius of the outer circle...

hope it makes sense

Answer 6

2.7 is a radi of the inner circle

Answer 7

added 2.7+2.2= 4.9

Answer 8

thats correct

and the outer...?

then the area of the deck = area of outer circle - area of the inner circle.

\[Area = \pi 4.9^2 - \pi 2.2^2\]

Answer 9

just calculate it out for the answer, the round to 1 decimal place...

Answer 10

Im still confsed

Answer 11

im trying to make this clearer for me so i canw rite it down for reference for later.

Answer 12

ok... so the deck is basically a large circle, with a smaller circle placed in the centre.

So if you find the area of the large circle, radius 4.9 then subtract the area of the small circle, 2.2, the difference is the area between the circles

Answer 13

oops should be

\[area = \pi \times 4.9^2 - \pi \times 2.7^2\]

sorry for the typo

Answer 14
