Answer:
The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14.
500/20 = 25kcal per piece
8 * 25 = 200kcal.....yes, he is able to have 8 pieces
3√10^4x is equivalent to -√10 3/4^x and -4√10^3x they are all equivalent
2^2=4 so divid 36/4 is 9 and 4*2=8 now subtract 9-8=1 next 36/1 = 36 same on top is 8 now 36-8=28. 28 - 8 is 20 then 20-8= 12 answer is 12
