Question

find the total surface area of a cone if it's slant height is 23m and diameter of its base is 24m​

Answer 1

Answer:

23*24 is your answer so the Radi will be able to make metres

Answer 2

Step-by-step explanation:

formula of TSA =

$\pi \: r(r + l)$

where r is radius and l is slant height.

Given that,

l =23m

D=24m

then r=D/2 so r = 12m

putting on formula we get,

22/7*12(35)

=22*5*12

=1320m
