Steps:

Given that Base radius(r) = 87 in and height(h) = 45 in

Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)

Substitute the values of the radius r = 87 in and height h = 45 in into the formula. Pi (π) is approximately equal to 3.14 .

$(π⋅(87))$⋅ $(87$ + $\sqrt{(87)^2 + (45)^2})$

Move 87 to the left of π.

$(87π)$⋅$ (87$ + $\sqrt{(87)^2 + (45)^2}$

Simplify each term

Raise 87 in to the power of 2 and 45 to the power of 2

$(87π)$⋅$ (87$ + $\sqrt{(7569.0) + (2025.0)}$ in

Add 7569.0 in and 2025.0 in

$(87π)$ in⋅$ (87$ + $\sqrt{(9594.0)}$ in

Multipy 87π in and 87 in

7569.0π in + (87π . $\sqrt9594.0$)in

Put the value of $\sqrt9594.0$ = 97.9489663 in formula

7569.0π in + (87π . 97.9489663) in

Mulitply the 87π and 97.9489663

7569.0π in + (8521.5600684π)

Add 7569.0π in and 8521.5600684π in

The result can be shown in multiple forms

Exact Form

Area = 16090.5600684π in

∴ Surface Area of Cone 87 in by 45 in is 16090.5600684π in2

Decimal Form

50524.3586149 in2

∴ Surface Area of Cylinder 87 in by 45 in is 50524.3586149 in2
