Surface Area of a Cone 79 foot by 64 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 79 foot by height 64 foot is 44817.2577253 foot².

Steps:

Given that Base radius(r) = 79 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 = 79 ft and height h = 64 ft into the formula. Pi (π) is approximately equal to 3.14 .

$(π⋅(79))$⋅ $(79$ + $\sqrt{(79)^2 + (64)^2})$

Move 79 to the left of π.

$(79π)$⋅$ (79$ + $\sqrt{(79)^2 + (64)^2}$

Simplify each term

Raise 79 ft to the power of 2 and 64 to the power of 2

$(79π)$⋅$ (79$ + $\sqrt{(6241.0) + (4096.0)}$ ft

Add 6241.0 ft and 4096.0 ft

$(79π)$ ft⋅$ (79$ + $\sqrt{(10337.0)}$ ft

Multipy 79π ft and 79 ft

6241.0π ft + (79π . $\sqrt10337.0$)ft

Put the value of $\sqrt10337.0$ = 101.6710382 in formula

6241.0π ft + (79π . 101.6710382) ft

Mulitply the 79π and 101.6710382

6241.0π ft + (8032.0120144π)

Add 6241.0π ft and 8032.0120144π ft

The result can be shown in multiple forms
