Surface Area of a Cone 73 foot by 29 foot 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 73 foot by height 29 foot is 34738.1414446 foot².

Steps:

Given that Base radius(r) = 73 ft and height(h) = 29 ft

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

Substitute the values of the radius r = 73 ft and height h = 29 ft into the formula. Pi (π) is approximately equal to 3.14 .

$(π⋅(73))$⋅ $(73$ + $\sqrt{(73)^2 + (29)^2})$

Move 73 to the left of π.

$(73π)$⋅$ (73$ + $\sqrt{(73)^2 + (29)^2}$

Simplify each term

Raise 73 ft to the power of 2 and 29 to the power of 2

$(73π)$⋅$ (73$ + $\sqrt{(5329.0) + (841.0)}$ ft

Add 5329.0 ft and 841.0 ft

$(73π)$ ft⋅$ (73$ + $\sqrt{(6170.0)}$ ft

Multipy 73π ft and 73 ft

5329.0π ft + (73π . $\sqrt6170.0$)ft

Put the value of $\sqrt6170.0$ = 78.5493475 in formula

5329.0π ft + (73π . 78.5493475) ft

Mulitply the 73π and 78.5493475

5329.0π ft + (5734.1023709π)

Add 5329.0π ft and 5734.1023709π ft

The result can be shown in multiple forms
