Answer: 63
Hopefully the work makes sense but basically you will add equation DE and EF to get 6x+11 then use that equation with DF and solve for x which will get 26/3 then plug it into DF to get 63

bc it sinple math if you think about it
Years of decay...
It takes around 4 years for something to go through their half life (depending on the thing). This chart is showing the years go by (half lives that occur within the years) while the decaying is happening.
Answer:
Note that surface is a triangle of base 3.14 * 14.8 = 46.6 cm
B / 2 = 23.2 cm 1/2 base
the height of triangle = 10 cm
A = 23.2 * 10 = 232 cm the area of the surface
Area formulas provides
A = Π r (r^2 + h^2)^1/2 which is the same as above
The quantity in brackets is just the slant height of 10 cm
