Steps:
Given that Base radius(r) = 82 ft and height(h) = 64 ft
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 82 ft and height h = 64 ft into the formula. Pi (π) is approximately equal to 3.14 .
$(π⋅(82))$⋅ $(82$ + $\sqrt{(82)^2 + (64)^2})$
Move 82 to the left of π.
$(82π)$⋅$ (82$ + $\sqrt{(82)^2 + (64)^2}$
Simplify each term
Raise 82 ft to the power of 2 and 64 to the power of 2
$(82π)$⋅$ (82$ + $\sqrt{(6724.0) + (4096.0)}$ ft
Add 6724.0 ft and 4096.0 ft
$(82π)$ ft⋅$ (82$ + $\sqrt{(10820.0)}$ ft
Multipy 82π ft and 82 ft
6724.0π ft + (82π . $\sqrt10820.0$)ft
Put the value of $\sqrt10820.0$ = 104.019229 in formula
6724.0π ft + (82π . 104.019229) ft
Mulitply the 82π and 104.019229
6724.0π ft + (8529.5767773π)
Add 6724.0π ft and 8529.5767773π ft
The result can be shown in multiple forms
