480 cubic inches should be the answer
Answer:
78.6
Step-by-step explanation:
Area of circle = Pi*r^2
r=5
for pi use calculator or pi=3.142
area =Pi*r2=(3.142)*5^2=(3.142)*25=78.55 = 78.6 (1 decimal place which is same with tenth)
(250 * 12) / 39,000 = 3000/39,000 which reduces to 1/13 <==
** I multiplied 250 by 12 to get the cost per yr
The correct is the second one
Answer:
D) 
Step-by-step explanation:
We have been given four choices.
A) 
B) 
C) 
D) 
Now we need to find about which of the above choices is a sum of cubes.
Basically we need to check which one of the given choices can be represented in cubic form along with addition sign.
3 and 9 can't be written in cubic form unless we use radical numbers.
So the only choice left is D)
D) 


which is clearly visible as sum of cubes.
