Well, it can be easily done by differentiating function of area with respect to one of either height or radii/diameter (if calculus is enabled).say:A=pi*r^2 + 2pi*r*hV=pi*r^2*h or h=V/(pi*r^2)thenA=pi*r^2 + 2pi*r*V/(pi*r^2)to minimize surface area, we make dA/dr = 0try to do the rest, you'll find 2r = h
First walk=descend of 1024 feet in 17 minutes
second walk=descend of 500 feet in 7 minutes
so in total she descended 1024+500=1524 feet in 7+17=24 minutes
as an average rate this equals 1524/24=63.5 feet/minute descended
or an average rate of -63.5 feet/minute in altitude (note the minus)
Solution: Since, it’s a standard cone opening up on the positive x- axis
Therefore, x=√y2+z2
She can spend a little over 30 dollars each day, ($30.35)
Gallons per day.......gallons / day.....so u put the gallons over the number of days, then divide
(1/2) / 6 = 1/2 * 1/6 = 1/12 of a gallon per day <==
