Steps:
Given that Base radius(r) = 9 yd and height(h) = 84 ft
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 9 yd and height h = 84 ft into the formula. Pi (π) is approximately equal to 3.14 .
Unit Conversion of 84 ft = 28.0 yd
84 Feet is 28.0 yards
To convert Feet to Yards
we know that, 1 Foot = 0.333333 or
1 Foot = 1/3 Yards
To convert Feet to Yards, divide the feet value by 3
Result in Yards: 84 × ft/yd × ft/yd
Cancel The Comman factor of ft
Result in Yards: 84/3 yd
Divide the 84 by 3
Result in Yards: 28.0 yards
∴ 84 Feet = 28.0 yards
$(π⋅(9))$⋅ $(9$ + $\sqrt{(9)^2 + (28.0)^2})$ yd
Move 9 to the left of π.
$(9π)$⋅$ (9$ + $\sqrt{(9)^2 + (28.0)^2}$
Simplify each term
Raise 9 yd to the power of 2 and 28.0 to the power of 2
$(9π)$⋅$ (9$ + $\sqrt{(81.0) + (784.0)}$ yd
Add 81.0 yd and 784.0 yd
$(9π)$ yd⋅$ (9$ + $\sqrt{(865.0)}$ yd
Multipy 9π yd and 9 yd
81.0π yd + (9π . $\sqrt{ 865.0 }$) yd
Put the value of $\sqrt{ 865.0 }$ = 29.4108823 in formula
81.0π yd + (9π . 29.4108823) yd
Mulitply the 9π and 29.4108823
81.0π yd + (264.6979411π)
Add 81.0π yd and 264.6979411π yd
The result can be shown in multiple forms
Exact Form
Area = 345.6979411π yd
∴ Surface Area of Cone 9 yd by 84 ft is 345.6979411π yd2
Decimal Form
1085.4915349 yd2
∴ Surface Area of Cylinder 9 yd by 84 ft is 1085.4915349 yd2
or
Unit Conversion of 9 yd = 27.0 ft
9 Yards is 27.0 foots
To convert Yards to Foot
we know that, 1 Yards = 3 Feet
To convert Yards to Foot, multiply the yard value by 3.
Result in Feet: 9 yd x 3 × ft/yd
Cancel The Comman factor of yd
Result in Feet: (9 x 3 ft)
Multiply 9 into 3
Result in Feet: 27.0 feets
∴ 9 Yards = 27.0 foots
$(π⋅(27.0))$⋅ $(27.0$ + $\sqrt{(27.0)^2 + (84)^2})$ ft
Move 27.0 to the left of π.
$(27.0π)$⋅$ (27.0$ + $\sqrt{(27.0)^2 + (84)^2}$
Simplify each term
Raise 27.0 ft to the power of 2 and 84 to the power of 2
$(27.0π)$⋅$ (27.0$ + $\sqrt{(729.0) + (7056.0)}$ ft
Add 729.0 ft and 7056.0 ft
$(27.0π)$ ft ⋅ $ (27.0$ + $\sqrt{(7785.0)}$ ft
Multipy 27.0π ft and 27.0 ft
729.0π ft + (27.0π . $\sqrt{ 7785.0 }$) ft
Put the value of $\sqrt{7785.0}$ = 88.232647 in formula
729.0π ft + (27.0π . 88.232647) ft
Mulitply the 27.0π and 88.232647
729.0π ft + (2382.2814695π)
Add 729.0π ft and 2382.2814695π ft
The result can be shown in multiple forms
Exact Form
Area = 3111.2814695π ft
∴ Surface Area of Cone 9 yd by 84 ft is 3111.2814695π yd2
Decimal Form
9769.4238143 ft2
∴ Surface Area of Cylinder 9 yd by 84 ft is 9769.4238143 yd2
