Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r
V = 4/3 π7^3
Evaluate the exponent
V = 4/3 π 343
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.
v= (4/3*343)π
v=1372/3π
If we want an exact answer, multiply 1372/3 and pi
v=1436.75504
So, the volume is 1436.75504 or 1372/3 π cm^3
Answer:
A={5,1,-7}
Step-by-step explanation:
domain = x
choose domain {-2,0,4} to 2x+y=1
range = y
range is
2(-2)+y =1 ,y =5
2(0)+y=1, y= 1
2(4)+ y=1, y=-7
range = {5,1,-7}
Answer:
y=4x-2
Step-by-step explanation:
y=mx+b
where m=slope and b=y-intercept.
y-6=4(x-2)
y-6=4x-8
y=4x-8+6
y=4x-2
Step-by-step explanation:
Given that,
For 4 weeks in June, Cameron biked 3 1/4 miles each week and swam 2 1/2 miles each week.
For 3 weeks in July, he biked 4 3/4 miles each week and swam 3 1/2 miles each week.
We need to find how much greater was the total distance Cameron bike and swim in July compared to the total distance he bike in swim in June.
In July, total distance is ,

In June, total distance is :

Hence, in June total distance is 23 miles and in July total distance is 24.75 miles.
