The answer would be A!
Whenever there is a fraction in the exponent, the numerator is under the square root, and the denominator is on the outside of the square root!
Additionally, since the negative is outside of the square toot, then it also outside of the parenthesis.
Answer:
i think its 10 if not then 387
Step-by-step explanation:
So Volume of cylinder is pi*r^2*h = 1,000
Then lightest one means you have the smallest surface area. Which is one base and then the area of the surface. SA = pi*r^2 + 2pi*r*h
So now you have 2 equations, so:
h = 1,000/(pi*r^2)
So then SA = pi*r^2 + 2pi*r*(1,000/(pi*r^2) = pi*r^2 + 2,000/r
Derivative of SA is then 2pi*r -2,000/r^2. Set to 0
2pi*r-2,000/r^2 =0 --> 2pi*r^3 = 2,000 --> r^3 = 1,000/pi --> r = 10/pi^(1/3)
Now go back to the volume function: pi*r^2*h =1,000 --> 1,000/(pi*100/pi^(2/3)) = h
<span>h = 10 / pi^(1/3)</span>
Answer:
1/5
Step-by-step explanation:
To simplify, we can first divide the top and bottom by 10:
2/10
Then by 2:
1/5
