A truncated cone is a part of a cone located between its base and a secant plane parallel to the base.
The formula for the area of the entire surface of the cone
where R is the radius of the lower base,r is the radius of the upper base, L is the length of the generatrix.
A truncated cone is a part of a cone located between its base and a secant plane parallel to the base.
The formula of the area of the lateral surface of the cone
where R is the radius of the lower base,r is the radius of the upper base, L is the length of the generatrix.
Solution:
S = π·(R2+(R+r)L+r2)
= π·(28802+(2880+2880)2880+28802)
= π·(8294400+5760·2880+8294400)
= π·(8294400+16588800+8294400)
= 33177600·π
=
104227430.4
a: The area of the entire surface of a truncated cone with the radius of the lower base R = 2880, with the radius of the upper base r = 2880, and the generative L = 2880 equal to 104227430.4
