Question

find the slant height of a cone with surface area 381.77 ft and radius 6.2 ft

campbell_st · Answer

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

anonymous · Answer

so S= 241.54

campbell_st · Answer

well to start you need to subtract the area of a circle then divide by 6.2 pi to find s

$$s= \frac{381.77 - \pi \times 6.2^2}{\pi \times 6.2}$$

anonymous · Answer

ok so 343.33/6.2 times pie

campbell_st · Answer

no do the calculation correctly 

$$s =\frac{(381.77 - 120.76)}{19.48}$$

anonymous · Answer

that equal 13.39
