Answer:
2^(5/2)
Step-by-step explanation:
2^0 = 1, so the given expression immediately becomes
2^3
------------ = 2^(5/2) (we subtract 1/2 from 3, obtaining 5/2)
2^(1/2)
I have no idea she got it wrong the real answer is 5
0.00356 is the standard form
Answer:
506.7 cm²
Step-by-step explanation:
The amount of cardboard needed would be the surface area of the cone,
S= pi(r)(l+r) where r is the radius and l is the slant height.
You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.
Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²
