Steps:
Given that Base radius(r) = 3 m and height(h) = 85 ft
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 3 m and height h = 85 ft into the formula. Pi (π) is approximately equal to 3.14 .
Unit Conversion of 85 ft = 25.908 m
85 Foot is 25.908 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: 85 ft × 0.3048 × m/ft
Cancel The Comman factor of ft
Result in Meters: (85 x 0.3048 m)
Multiply 85 into 0.3048
Result in Meters: 25.908 meters
∴ 85 Foot = 25.908 meters
$(π⋅(3))$⋅ $(3$ + $\sqrt{(3)^2 + (25.908)^2})$ m
Move 3 to the left of π.
$(3π)$⋅$ (3$ + $\sqrt{(3)^2 + (25.908)^2}$
Simplify each term
Raise 3 m to the power of 2 and 25.908 to the power of 2
$(3π)$⋅$ (3$ + $\sqrt{(9.0) + (671.224464)}$ m
Add 9.0 m and 671.224464 m
$(3π)$ m⋅$ (3$ + $\sqrt{(680.224464)}$ m
Multipy 3π m and 3 m
9.0π m + (3π . $\sqrt{ 680.224464 }$) m
Put the value of $\sqrt{ 680.224464 }$ = 26.0811132 in formula
9.0π m + (3π . 26.0811132) m
Mulitply the 3π and 26.0811132
9.0π m + (78.2433395π)
Add 9.0π m and 78.2433395π m
The result can be shown in multiple forms
Exact Form
Area = 87.2433395π m
∴ Surface Area of Cone 3 m by 85 ft is 87.2433395π m2
Decimal Form
273.944086 m2
∴ Surface Area of Cylinder 3 m by 85 ft is 273.944086 m2

Unit Conversion of 3 m = 9.84252 ft
3 Meters is 9.84252 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: 3 m × 3.28084 × ft/m
Cancel The Comman factor of m
Result in Foot: (3 x 3.28084 ft)
Multiply 3 into 3.28084
Result in Foot: 9.84252 foot
∴ 3 Meters = 9.84252 foot
$(π⋅(9.84252))$⋅ $(9.84252$ + $\sqrt{(9.84252)^2 + (85)^2})$ ft
Move 9.84252 to the left of π.
$(9.84252π)$⋅$ (9.84252$ + $\sqrt{(9.84252)^2 + (85)^2}$
Simplify each term
Raise 9.84252 ft to the power of 2 and 85 to the power of 2
$(9.84252π)$⋅$ (9.84252$ + $\sqrt{(96.87519995) + (7225.0)}$ ft
Add 96.8752 ft and 7225.0 ft
$(9.84252π)$ ft ⋅ $ (9.84252$ + $\sqrt{(7321.8752)}$ ft
Multipy 9.84252π ft and 9.84252 ft
96.8752π ft + (9.84252π . $\sqrt{ 7321.8752 }$) ft
Put the value of $\sqrt{7321.8752}$ = 85.5679566 in formula
96.8752π ft + (9.84252π . 85.5679566) ft
Mulitply the 9.84252π and 85.5679566
96.8752π ft + (842.2043244π)
Add 96.8752π ft and 842.2043244π ft
The result can be shown in multiple forms
