Steps:
Given that Base radius(r) = 42 ft and height(h) = 39 yd
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 42 ft and height h = 39 yd into the formula. Pi (π) is approximately equal to 3.14 .
Unit Conversion of 39 yd = 117.0 ft
39 Yards is 117.0 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: 39 yd x 3 × ft/yd
Cancel The Comman factor of yd
Result in Feet: (39 x 3 ft)
Multiply 39 into 3
Result in Feet: 117.0 feets
∴ 39 Yards = 117.0 foots
$(π⋅(42))$⋅ $(42$ + $\sqrt{(42)^2 + (117.0)^2})$ ft
Move 42 to the left of π.
$(42π)$⋅$ (42$ + $\sqrt{(42)^2 + (117.0)^2}$
Simplify each term
Raise 42 ft to the power of 2 and 117.0 to the power of 2
$(42π)$⋅$ (42$ + $\sqrt{(1764.0) + (13689.0)}$ ft
Add 1764.0 ft and 13689.0 ft
$(42π)$ ft⋅$ (42$ + $\sqrt{(15453.0)}$ ft
Multipy 42π ft and 42 ft
1764.0π ft + (42π . $\sqrt{ 15453.0 }$) ft
Put the value of $\sqrt{ 15453.0 }$ = 124.3100961 in formula
1764.0π ft + (42π . 124.3100961) ft
Mulitply the 42π and 124.3100961
1764.0π ft + (5221.0240375π)
Add 1764.0π ft and 5221.0240375π ft
The result can be shown in multiple forms
Exact Form
Area = 6985.0240375π ft
∴ Surface Area of Cone 42 ft by 39 yd is 6985.0240375π ft2
Decimal Form
21932.9754777 ft2
∴ Surface Area of Cylinder 42 ft by 39 yd is 21932.9754777 ft2
or
Unit Conversion of 42 ft = 14.0 yd
42 Feet is 14.0 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: 42 × ft/yd × ft/yd
Cancel The Comman factor of ft
Result in Yards: 42/3 yd
Divide the 42 by 3
Result in Yards: 14.0 yards
∴ 42 Feet = 14.0 yards
$(π⋅(14.0))$⋅ $(14.0$ + $\sqrt{(14.0)^2 + (39)^2})$ yd
Move 14.0 to the left of π.
$(14.0π)$⋅$ (14.0$ + $\sqrt{(14.0)^2 + (39)^2}$
Simplify each term
Raise 14.0 yd to the power of 2 and 39 to the power of 2
$(14.0π)$⋅$ (14.0$ + $\sqrt{(196.0) + (1521.0)}$ yd
Add 196.0 yd and 1521.0 yd
$(14.0π)$ yd ⋅ $ (14.0$ + $\sqrt{(1717.0)}$ yd
Multipy 14.0π yd and 14.0 yd
196.0π yd + (14.0π . $\sqrt{ 1717.0 }$) yd
Put the value of $\sqrt{1717.0}$ = 41.4366987 in formula
196.0π yd + (14.0π . 41.4366987) yd
Mulitply the 14.0π and 41.4366987
196.0π yd + (580.1137819π)
Add 196.0π yd and 580.1137819π yd
The result can be shown in multiple forms
Exact Form
Area = 776.1137819π yd
∴ Surface Area of Cone 42 ft by 39 yd is 776.1137819π ft2
Decimal Form
2436.9972753 yd2
∴ Surface Area of Cylinder 42 ft by 39 yd is 2436.9972753 ft2
