Answer:
C. 78.5 in^3
Step-by-step explanation:
A soup can is in the shape of a cylinder. The volume of a cylinder can be found using the following formula:
We know that the height is 4 inches and the radius is 2.5 inches.
r= 2.5 in
h= 4 in
Evaluate the exponent.
Multiply 6.25 in^2 and 4 in.
Multiply pi and 25 in^3.
Round to the nearest tenth. The 3 in the hundredth place tells us to leave the 5 in the tenth place.
78.5 cubic inches can fill one soup can.
Answer:
1120 Eagles
Step-by-step explanation:
If the population of Eagles decreases by 4% percent each year, then in 2030 (which is 15 years later), the population would decrease by (4 × 15)%
that is 60%
This indicates that the population of bald eagles in the year 2030 would be 60% less of what it was in the year 2015.
so we have, × 2800
which gives us 1680
this means that the number of bald eagles in the year 2030 would be 1680 less than the number of bald eagles in the year 2015
hence 2800 - 1680
then the answer is 1120 Bald Eagles
