Steps:
Given that Base radius(r) = 21 ft and height(h) = 63 m
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 21 ft and height h = 63 m into the formula. Pi (π) is approximately equal to 3.14 .
Unit Conversion of 63 m = 206.69292 ft
63 Meters is 206.69292 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: 63 m × 3.28084 × ft/m
Cancel The Comman factor of m
Result in Foot: (63 x 3.28084 ft)
Multiply 63 into 3.28084
Result in Foot: 206.69292 foot
∴ 63 Meters = 206.69292 foot
$(π⋅(21))$⋅ $(21$ + $\sqrt{(21)^2 + (206.69292)^2})$ ft
Move 21 to the left of π.
$(21π)$⋅$ (21$ + $\sqrt{(21)^2 + (206.69292)^2}$
Simplify each term
Raise 21 ft to the power of 2 and 206.69292 to the power of 2
$(21π)$⋅$ (21$ + $\sqrt{(441.0) + (42721.9631781)}$ ft
Add 441.0 ft and 42721.9631781 ft
$(21π)$ ft⋅$ (21$ + $\sqrt{(43162.9631781)}$ ft
Multipy 21π ft and 21 ft
441.0π ft + (21π . $\sqrt{ 43162.9631781 }$) ft
Put the value of $\sqrt{ 43162.9631781 }$ = 207.7569811 in formula
441.0π ft + (21π . 207.7569811) ft
Mulitply the 21π and 207.7569811
441.0π ft + (4362.8966022π)
Add 441.0π ft and 4362.8966022π ft
The result can be shown in multiple forms
Exact Form
Area = 4803.8966022π ft
∴ Surface Area of Cone 21 ft by 63 m is 4803.8966022π ft2
Decimal Form
15084.2353309 ft2
∴ Surface Area of Cylinder 21 ft by 63 m is 15084.2353309 ft2

Unit Conversion of 21 ft = 6.4008 m
21 Foot is 6.4008 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: 21 ft × 0.3048 × m/ft
Cancel The Comman factor of ft
Result in Meters: (21 x 0.3048 m)
Multiply 21 into 0.3048
Result in Meters: 6.4008 meters
∴ 21 Foot = 6.4008 meters
$(π⋅(6.4008))$⋅ $(6.4008$ + $\sqrt{(6.4008)^2 + (63)^2})$ m
Move 6.4008 to the left of π.
$(6.4008π)$⋅$ (6.4008$ + $\sqrt{(6.4008)^2 + (63)^2}$
Simplify each term
Raise 6.4008 m to the power of 2 and 63 to the power of 2
$(6.4008π)$⋅$ (6.4008$ + $\sqrt{(40.97024064) + (3969.0)}$ m
Add 40.9702406 m and 3969.0 m
$(6.4008π)$ m ⋅ $ (6.4008$ + $\sqrt{(4009.9702406)}$ m
Multipy 6.4008π m and 6.4008 m
40.9702406π m + (6.4008π . $\sqrt{ 4009.9702406 }$) m
Put the value of $\sqrt{4009.9702406}$ = 63.3243258 in formula
40.9702406π m + (6.4008π . 63.3243258) m
Mulitply the 6.4008π and 63.3243258
40.9702406π m + (405.3263447π)
Add 40.9702406π m and 405.3263447π m
The result can be shown in multiple forms
