This should help you here are the steps of your problem :)
2*(1/2)*r+2*r+1 = 9*(1/10) // - 9*(1/10)
2*(1/2)*r+2*r-(9*(1/10))+1 = 0
2*(1/2)*r+2*r-9/10+1 = 0
3*r+1/10 = 0 // - 1/10
3*r = -1/10 // : 3
r = -1/10/3
r = -1/30
r = -1/30
So your answer would be 1/30
Answer:
The formula for the volume of a sphere is V = 4/3 πr³
Step-by-step explanation:
If it is said that the range of the answer should be +/- 10% of the particular value, we have to find out the percentage of that particular value. Therefore 10% of 1.8 is,
1.8 * 10/100 = 0.18
If we add this value to the original value,
1.8+0.18 = 1.98
If we subtract this value from the original value,
<span>1.8-0.18 = 1.62
</span>
therefore the range will be,
from 1.62 to 1.98
