Area_{circle}=\pi r^{2}
Area_{circle} = \pi (pool+walkway)^{2}
Area_{circle} = \pi (\frac{30}{2}+4)^{2}
Area_{circle} = \pi (19)^{2}
Area_{circle} = \pi (19)^{2}=361 \pi \approx 1134.11

Area_{rectangle}=lw
Area_{rectangle}=(l_{pool}+2(walkway))\times(w_{pool}+2(walkway))
Area_{rectangle}=(16+2(3))\times(40+2(3))
Area_{rectangle}=22\times46
Area_{rectangle}=1012

Area_{yard}=lw=75\times50=3750

With round:
Area_{GrassAvailable}=A_{yard}-A_{circle}
Area_{GrassAvailable}=3750-1134.11=2615.89

With rectangle:
Area_{GrassAvailable}=A_{yard}-A_{rectangle}
Area_{GrassAvailable}=3750-1012=2738

A swim team is divided into age groups: Guppies, stingrays, and sharks. There are 20 swimmers in the Stingray group. If we rando
ivanzaharov [21]

If you choose 10 swimmers and 4 are Stingrays, you can say that Stingrays make up roughly 40% of the swimmers. If 20 Stingrays make up 40% of all the swimmers, we just have to find what number 20 is 40% of. That’s easy enough by cross multiplication:

20/x = 40/100

20/x = 4/10

20/x = 2/5

x = 50.

Double check by multiplying 50 * 0.4. Since 50 * 0.4 = 20, we know we have the right answer. There are about 50 swimmers on this team.
