Question

The total surface area of a cone is 704 sq.cm and radius of its base is 7 cm, find the

slant height of the cone. ( =

22 )

7​

Answer 1

Step-by-step explanation:

area=1/3h*r=704

1/3*h*7=704

h=704*3/7=301.71cm

slant height=(301.71²+7²)½=301.79≈302cm

Answer 2

Answer:

$tsa \: of \: cone \: = \pi \: r(l + r) \\ 704 = \frac{22}{7} \times 7(l + 7) \\ 704 = 22(l + 7) \\ \frac{704}{22} = (l + 7) \\ 32 - 7 = l \\ 25 = l \\ \\ please \: mark \: as \: brainliest \: \\ i \: want \: only \: one \: brainliest \: answer \: to \: reach \: at \: the \: next \: level$
