As the hint suggests, convert to spherical coordinates using
x = p cos(u) sin(v)
y = p sin(u) sin(v)
z = p cos(v)
dV = dx dy dz = p² sin(v) dp du dv
Then U is the set

and the integral of y over U is







To the nearest 10: 26630
To the nearest 100: 26600
To the nearest 1000: 27000
If the number after the tens/hundreds/thousands unit is under five, you round down. If the number after is five or above, you round up.
Hope I helped, although the question is a bit ambiguous and there is no picture of a number line.
1. sum of a number plus 6 is 7 times the number:
n+6 = 7n
2. qoutent of a number and 5 is 8
n/5 =8
n = 5*8
n = 40
3. distance = speed times time
so d = 55t
The answer is 19 please like and 5 star
