Surface Area of a Cone 89 inches by 44 inches Calculator

The surface area of a cone is equal to the area of the base plus the area of the cone. If the cone Radius 89 inches by height 44 inches is 52617.4066117 inches².

Steps:

Given that Base radius(r) = 89 in and height(h) = 44 in

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

Substitute the values of the radius r = 89 in and height h = 44 in into the formula. Pi (π) is approximately equal to 3.14 .

$(π⋅(89))$⋅ $(89$ + $\sqrt{(89)^2 + (44)^2})$

Move 89 to the left of π.

$(89π)$⋅$ (89$ + $\sqrt{(89)^2 + (44)^2}$

Simplify each term

Raise 89 in to the power of 2 and 44 to the power of 2

$(89π)$⋅$ (89$ + $\sqrt{(7921.0) + (1936.0)}$ in

Add 7921.0 in and 1936.0 in

$(89π)$ in⋅$ (89$ + $\sqrt{(9857.0)}$ in

Multipy 89π in and 89 in

7921.0π in + (89π . $\sqrt9857.0$)in

Put the value of $\sqrt9857.0$ = 99.2824254 in formula

7921.0π in + (89π . 99.2824254) in

Mulitply the 89π and 99.2824254

7921.0π in + (8836.1358636π)

Add 7921.0π in and 8836.1358636π in

The result can be shown in multiple forms
