Answer:
18 hdhb
Step-by-step explanation:
1. The Formula to getting the area of a circle is pi r^2= 3.14 times the radius squared. Plug in the number given in the question to get your answer.
2. The Circumference formula is 2pir which is 2 time 3.14 times the radius given. Plug in the number to get your answer.
3. This one is giving you the diameter, therefore you need to divide the diameter by 2 to get the radius (diameter is twice the size of radius) and plug in the radius into the first formula (3.14 times r^2) to get your answer.
Answer:
a. We need 1/4 for each feeder
b. To fill each feeder we need 1.25 pounds
c. We need 60 ounces to fill three bird feeders
Step-by-step explanation:
Five pounds of birdseed is used to fill 4 identical bird feeders,
a. We divide all the birdseed in 4 feeders, so, we need 1/4 for each feeder.
b. If we use 5 pounds for the 4 feeders, so each feeders will take 1/4 of the 5 pounds
=1/4 x 5=1.25 pounds
c. To fill three bird feeders we have to multiply the amount of pounds by feeder by 3 feeders
=1.25 pounds x 3
= 3,75 pounds
If 16 ounces are a pound
so, 16 x 3.75 = 60 ounces
No. If you do 6+1/3 and 24+1/3 it is not equal.
