Answer:

243.37 in^2

Step-by-step explanation:

large rectangle=28x15=420  (now we need to deduct the circular areas)

circular area =7.5^2(3.14)=176.63  (radius^2xPi)   (this is for a full circle which accounts for the two semi circles)

420-176.63=243.37

ioda

Answer:The new cost per person= $19 when there are 12 people

Step-by-step explanation:

Step 1

Let Number of people be rep as N

And Cost per person = C

such that the relationship of  number of people which varies inversely with the cost per person is given as

N∝ 1/C

Introducing constant of proportionality, k, we have that

N= K/C

such that when there were 4 people the cost per person was $57, K would be

N= K/C

4 = K /57

k= 57 X 4

k=228

Step 2

Therefore If the number of people changed to 12, cost per person would be

N= K/C

12= 228 / C

C= 228/12

C= 19

The new cost per person= $19 when there are 12 people
