Question

Find the area for each circle with a diameter of 11ft.
A. 90 ft2
B. 95 ft2
C. 97 ft2
D. 99 ft2

Answer 1

If the diameter is 11 ft, then the radius is half that at r = 11/2 = 5.5 feet

Now plug this into the formula A = pi*r^2

A = pi*r^2

A = pi*(5.5)^2

A = (3.14)*(5.5)^2

I'll let you finish

Answer 2

That doesn't seem right... how many circle are there?

Answer 3

the formula and set up is correct... just multiply your answer by however many circles there are to get the final answer.

Answer 4

There iss no picture thoee o; . . thats thee whole problemm .

Answer 5

Hm... cuz in your question it says find the area for EACH circle.... :/

With the given diameter and set up, your answer should be 30.25... I would go with A. Because you can assume that there are 3 circles... with is appx. 90.75 thus making the other options invalid

Answer 6

not sure how you're getting 30.25 since (3.14)*(5.5)^2 = 94.985

Answer 7

Isnt 95 feet ?

Answer 8

My bad, you should go with B, my error i forgot to multiple pi.

Answer 9

yes so it's closest to 95 square feet

Answer 10

if you round too the wholee number ?

Answer 11

yes

Answer 12

Thank youuu (:
