Steps:
Given that Base radius(r) = 77 ft and height(h) = 67 ft
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 77 ft and height h = 67 ft into the formula. Pi (π) is approximately equal to 3.14 .
$(π⋅(77))$⋅ $(77$ + $\sqrt{(77)^2 + (67)^2})$
Move 77 to the left of π.
$(77π)$⋅$ (77$ + $\sqrt{(77)^2 + (67)^2}$
Simplify each term
Raise 77 ft to the power of 2 and 67 to the power of 2
$(77π)$⋅$ (77$ + $\sqrt{(5929.0) + (4489.0)}$ ft
Add 5929.0 ft and 4489.0 ft
$(77π)$ ft⋅$ (77$ + $\sqrt{(10418.0)}$ ft
Multipy 77π ft and 77 ft
5929.0π ft + (77π . $\sqrt10418.0$)ft
Put the value of $\sqrt10418.0$ = 102.0686044 in formula
5929.0π ft + (77π . 102.0686044) ft
Mulitply the 77π and 102.0686044
5929.0π ft + (7859.2825372π)
Add 5929.0π ft and 7859.2825372π ft
The result can be shown in multiple forms
