Answer:
Step-by-step explanation:
We have been given that at a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m.
To find the area of the side walk we will subtract the area of inner edge of the side walk of lion pen from the area of the outer edge of the lion pen.
, where r represents radius of the circle.
Therefore, the exact area of the side walk is 
To find the approximate area of side walk let us substitute pi equals 3.14.
Therefore, the approximate area of the side walk is 
.
16*18 is 288

Answer:
D
Step-by-step explanation:
<span>1) If you invest $2,000.00 at a rate of 4% APR for 3 months and the interest is compounded monthly then in 3 months.It will be worth $2,020.07.
So subtracting $2,000 from $ 2,020.07
we get.
<span>$20.07
2) </span></span><span>I = Prt </span>
<span>I = 4,000 * 0.05 </span>
<span>I = $200
</span><span>200 / 10 = 20 hours of work</span>
Yes. For example, 25. The square root of 25 is 5 because 5*5=25. Multiplying two negatives always= a positive, so -5*-5=25.
