Question

PLEASE HELP FOR TEST will mark brainiest !!

Answer 1

Answer:

552.920307 yd^2 or 552.92 yd^2 for sigfigs

Step-by-step explanation:

basically you take the area of the entire circle and subtract the interior circle to leave the ring and that’s your answer

so the area formula of a circle is π r^2

the radius (r) is just half the diameter so the entire diameter is 48 so the radius is 24 - π(24)^2 = 1809.557368^2

then the interior circle’s diameter is 40 so the radius is 20 - π(20)^2 = 1256.637061^2

so now it’s just subtraction:

1809.557368 yd^2 - 1256.637061 yd^2 =
552.920307 yd^2 or 552.92 yd^2 for sigfigs

hope this helps :)

Answer 2

Answer:

552 yd squared

Step-by-step explanation:

We first find the entire area of the circle which should look like this:

24^2(3.14) = 1808
keep in mind that the formula for finding the area of a circle is r^2(3.14)

Next we get the area of the inner circle which should look like this:

20^2(3.14) = 1256

Now the final step is to subtract 1256 from 1808. You will now get 552 yd squared as your final answer!
