In the equation for surface area the radius is squared ( r^2)
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.
If it simple interest it’s 2 years
The first one is 10ab + 20
7 days a week
4x7=28
About 4 weeks each month
28x4=112
The answer should be 112 hours. I hope this helped
