Steps:
Given that Base radius(r) = 18 ft and height(h) = 66 m
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 18 ft and height h = 66 m into the formula. Pi (π) is approximately equal to 3.14 .
Unit Conversion of 66 m = 216.53544 ft
66 Meters is 216.53544 foot
To convert Meters to Foot
we know that, 1 Meter = 3.28084 Foot
To convert Meter to Foot, multiply the meter value by 3.28084.
Result in Foot: 66 m × 3.28084 × ft/m
Cancel The Comman factor of m
Result in Foot: (66 x 3.28084 ft)
Multiply 66 into 3.28084
Result in Foot: 216.53544 foot
∴ 66 Meters = 216.53544 foot
$(π⋅(18))$⋅ $(18$ + $\sqrt{(18)^2 + (216.53544)^2})$ ft
Move 18 to the left of π.
$(18π)$⋅$ (18$ + $\sqrt{(18)^2 + (216.53544)^2}$
Simplify each term
Raise 18 ft to the power of 2 and 216.53544 to the power of 2
$(18π)$⋅$ (18$ + $\sqrt{(324.0) + (46887.596776)}$ ft
Add 324.0 ft and 46887.596776 ft
$(18π)$ ft⋅$ (18$ + $\sqrt{(47211.596776)}$ ft
Multipy 18π ft and 18 ft
324.0π ft + (18π . $\sqrt{ 47211.596776 }$) ft
Put the value of $\sqrt{ 47211.596776 }$ = 217.2822974 in formula
324.0π ft + (18π . 217.2822974) ft
Mulitply the 18π and 217.2822974
324.0π ft + (3911.0813537π)
Add 324.0π ft and 3911.0813537π ft
The result can be shown in multiple forms
Exact Form
Area = 4235.0813537π ft
∴ Surface Area of Cone 18 ft by 66 m is 4235.0813537π ft2
Decimal Form
13298.1554507 ft2
∴ Surface Area of Cylinder 18 ft by 66 m is 13298.1554507 ft2

Unit Conversion of 18 ft = 5.4864 m
18 Foot is 5.4864 meters
To convert Feet to Meter
we know that, 1 Foot = 0.3048 Meter
To convert Foot to meters, multiply the feet value by 0.3048.
Result in Meter: 18 ft × 0.3048 × m/ft
Cancel The Comman factor of ft
Result in Meters: (18 x 0.3048 m)
Multiply 18 into 0.3048
Result in Meters: 5.4864 meters
∴ 18 Foot = 5.4864 meters
$(π⋅(5.4864))$⋅ $(5.4864$ + $\sqrt{(5.4864)^2 + (66)^2})$ m
Move 5.4864 to the left of π.
$(5.4864π)$⋅$ (5.4864$ + $\sqrt{(5.4864)^2 + (66)^2}$
Simplify each term
Raise 5.4864 m to the power of 2 and 66 to the power of 2
$(5.4864π)$⋅$ (5.4864$ + $\sqrt{(30.10058496) + (4356.0)}$ m
Add 30.100585 m and 4356.0 m
$(5.4864π)$ m ⋅ $ (5.4864$ + $\sqrt{(4386.100585)}$ m
Multipy 5.4864π m and 5.4864 m
30.100585π m + (5.4864π . $\sqrt{ 4386.100585 }$) m
Put the value of $\sqrt{4386.100585}$ = 66.2276422 in formula
30.100585π m + (5.4864π . 66.2276422) m
Mulitply the 5.4864π and 66.2276422
30.100585π m + (363.3513359π)
Add 30.100585π m and 363.3513359π m
The result can be shown in multiple forms
