Keeping in mind that the area of a circle is πr².
the actual area will just be the area of the rectangular backyard plus the pool, namely (10*20) + (π15²), which gives us an actual area of
200 + 225π.
now, we know the model and actual are on a 1:20 ratio.
10.3225806452 is the corect answer
Because you are given the ingredients for one batch, and you want the ingredients for four batches, you can multiply all of the original quantities by 4 to find the answers.
1 1/2 × 4
To do this, first convert 1 1/2 into a mixed number by doing 1 × 2 = 2, and 2 + 1 = 3, which would be the numerator. This then gives you
3/2 × 4/1, which simplifies to 12/2, which means your answer is 6.
1 × 4 = 4
1 × 4 = 4
3 × 4 = 12
3/4 × 4 = 3
(you cancel out the "/4" because you're multiplying by 4)
1 × 4 = 4
1/3 × 4/1 = 4/3
I hope this helps!
