1 answer:
30% = 0.3
Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.
Solution:
To write percent to decimal, divide the number by 100.
= 0.3
30% = 0.3
Average use of water each day = 90 gallons
= 27
Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.

Circular pen means you are going to use Area = Pi(r^2).
So 78.5 = pi(r^2). Divide by pi on both sides to get r^2 = 78.5/pi. Take the square root of that to get r or radius = approximately 4.99. If you need an exact answer then use
for the next part because you are not done yet.
Plug whatever R you use into the circumference formula of Circumference = 2(pi)(r).
If you use 4.99, you do 2(pi)(4.99) which is approximately 31.35. If you use the exact answer, you do 2(pi)(
) which gives you approximately 31.41.
Either way you'll need about 31 meters of chicken wire but the 31.40796 or ~31.41 is closer to the exact answer.
