Steps:
Given that Base radius(r) = 21 ft and height(h) = 49 yd
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 = 49 yd into the formula. Pi (π) is approximately equal to 3.14 .
Unit Conversion of 49 yd = 147.0 ft
49 Yards is 147.0 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: 49 yd x 3 × ft/yd
Cancel The Comman factor of yd
Result in Feet: (49 x 3 ft)
Multiply 49 into 3
Result in Feet: 147.0 feets
∴ 49 Yards = 147.0 foots
$(π⋅(21))$⋅ $(21$ + $\sqrt{(21)^2 + (147.0)^2})$ ft
Move 21 to the left of π.
$(21π)$⋅$ (21$ + $\sqrt{(21)^2 + (147.0)^2}$
Simplify each term
Raise 21 ft to the power of 2 and 147.0 to the power of 2
$(21π)$⋅$ (21$ + $\sqrt{(441.0) + (21609.0)}$ ft
Add 441.0 ft and 21609.0 ft
$(21π)$ ft⋅$ (21$ + $\sqrt{(22050.0)}$ ft
Multipy 21π ft and 21 ft
441.0π ft + (21π . $\sqrt{ 22050.0 }$) ft
Put the value of $\sqrt{ 22050.0 }$ = 148.492424 in formula
441.0π ft + (21π . 148.492424) ft
Mulitply the 21π and 148.492424
441.0π ft + (3118.340905π)
Add 441.0π ft and 3118.340905π ft
The result can be shown in multiple forms
Exact Form
Area = 3559.340905π ft
∴ Surface Area of Cone 21 ft by 49 yd is 3559.340905π ft2
Decimal Form
11176.3304418 ft2
∴ Surface Area of Cylinder 21 ft by 49 yd is 11176.3304418 ft2
or
Unit Conversion of 21 ft = 7.0 yd
21 Feet is 7.0 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: 21 × ft/yd × ft/yd
Cancel The Comman factor of ft
Result in Yards: 21/3 yd
Divide the 21 by 3
Result in Yards: 7.0 yards
∴ 21 Feet = 7.0 yards
$(π⋅(7.0))$⋅ $(7.0$ + $\sqrt{(7.0)^2 + (49)^2})$ yd
Move 7.0 to the left of π.
$(7.0π)$⋅$ (7.0$ + $\sqrt{(7.0)^2 + (49)^2}$
Simplify each term
Raise 7.0 yd to the power of 2 and 49 to the power of 2
$(7.0π)$⋅$ (7.0$ + $\sqrt{(49.0) + (2401.0)}$ yd
Add 49.0 yd and 2401.0 yd
$(7.0π)$ yd ⋅ $ (7.0$ + $\sqrt{(2450.0)}$ yd
Multipy 7.0π yd and 7.0 yd
49.0π yd + (7.0π . $\sqrt{ 2450.0 }$) yd
Put the value of $\sqrt{2450.0}$ = 49.4974747 in formula
49.0π yd + (7.0π . 49.4974747) yd
Mulitply the 7.0π and 49.4974747
49.0π yd + (346.4823228π)
Add 49.0π yd and 346.4823228π yd
The result can be shown in multiple forms
Exact Form
Area = 395.4823228π yd
∴ Surface Area of Cone 21 ft by 49 yd is 395.4823228π ft2
Decimal Form
1241.8144935 yd2
∴ Surface Area of Cylinder 21 ft by 49 yd is 1241.8144935 ft2
