Question

find the slant height of a cone with surface area 381.77 ft and radius 6.2 ft
ill become your fan and give you an award

Answer 1

well the formula is

\[S.A. = \pi r s + \pi r^2\]

r = radius and s = slant height

so substituting your known information

\[381.77 = \pi \times 6.2 \times s + \pi \times 6.2^2\]

just solve the equation for s

Answer 2

so S= 241.54

Answer 3

well to start you need to subtract the area of a circle then divide by 6.2 pi to find s

\[s= \frac{381.77 - \pi \times 6.2^2}{\pi \times 6.2}\]

Answer 4

ok so 343.33/6.2 times pie

Answer 5

no do the calculation correctly

\[s =\frac{(381.77 - 120.76)}{19.48}\]

Answer 6

that equal 13.39
