Steps:
Given that Base radius(r) = 84 ft and height(h) = 23 ft
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 84 ft and height h = 23 ft into the formula. Pi (π) is approximately equal to 3.14 .
$(π⋅(84))$⋅ $(84$ + $\sqrt{(84)^2 + (23)^2})$
Move 84 to the left of π.
$(84π)$⋅$ (84$ + $\sqrt{(84)^2 + (23)^2}$
Simplify each term
Raise 84 ft to the power of 2 and 23 to the power of 2
$(84π)$⋅$ (84$ + $\sqrt{(7056.0) + (529.0)}$ ft
Add 7056.0 ft and 529.0 ft
$(84π)$ ft⋅$ (84$ + $\sqrt{(7585.0)}$ ft
Multipy 84π ft and 84 ft
7056.0π ft + (84π . $\sqrt7585.0$)ft
Put the value of $\sqrt7585.0$ = 87.0919055 in formula
7056.0π ft + (84π . 87.0919055) ft
Mulitply the 84π and 87.0919055
7056.0π ft + (7315.7200603π)
Add 7056.0π ft and 7315.7200603π ft
The result can be shown in multiple forms
