Steps:
Given that Base radius(r) = 7 m and height(h) = 12 in
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 7 m and height h = 12 in into the formula. Pi (π) is approximately equal to 3.14 .
Unit Conversion of 12 in = 0.3048 m
12 inches is 0.3048 meters
To convert inches to meter
we know that, 1 inch = 0.0254 meters
To convert inches to meter,multiply the inches value by 0.0254.
Result in Inches: 12 in x 0.0254 × m/in
Cancel The Comman factor of m
Result in Meters: (12 x 0.0254 m)
Multiply 12 into 0.0254
Result in meters: 0.3048 meters
∴ 12 inches = 0.3048 meters
$(π⋅(7))$⋅ $(7$ + $\sqrt{(7)^2 + (0.3048)^2})$ m
Move 7 to the left of π.
$(7π)$⋅$ (7$ + $\sqrt{(7)^2 + (0.3048)^2}$
Simplify each term
Raise 7 m to the power of 2 and 0.3048 to the power of 2
$(7π)$⋅$ (7$ + $\sqrt{(49.0) + (0.092903)}$ m
Add 49.0 m and 0.092903 m
$(7π)$ m⋅$ (7$ + $\sqrt{(49.092903)}$ m
Multipy 7π m and 7 m
49.0π m + (7π . $\sqrt{ 49.092903 }$) m
Put the value of $\sqrt{ 49.092903 }$ = 7.0066328 in formula
49.0π m + (7π . 7.0066328) m
Mulitply the 7π and 7.0066328
49.0π m + (49.0464295π)
Add 49.0π m and 49.0464295π m
The result can be shown in multiple forms
Exact Form
Area = 98.0464295π m
∴ Surface Area of Cone 7 m by 12 in is 98.0464295π m2
Decimal Form
307.8657887 m2
∴ Surface Area of Cylinder 7 m by 12 in is 307.8657887 m2

Unit Conversion of 7 m = 275.59 in
7 meter is 275.59 inches
To convert Meters to Inches
we know that, 1 Meter = 39.37 Inch
To convert meter to Inch,multiply the meter value by 39.37.
Result in Inches: 7 m × 39.37 × in/m
Cancel The Comman factor of m
Result in Inches: (7 * 39.37 in)
Multiply 275.59 into 39.37
∴ 7 meter = 275.59 inches
$(π⋅(275.59))$⋅ $(275.59$ + $\sqrt{(275.59)^2 + (12)^2})$ in
Move 275.59 to the left of π.
$(275.59π)$⋅$ (275.59$ + $\sqrt{(275.59)^2 + (12)^2}$
Simplify each term
Raise 275.59 in to the power of 2 and 12 to the power of 2
$(275.59π)$⋅$ (275.59$ + $\sqrt{(75949.8481) + (144.0)}$ in
Add 75949.8481 in and 144.0 in
$(275.59π)$ in ⋅ $ (275.59$ + $\sqrt{(76093.8481)}$ in
Multipy 275.59π in and 275.59 in
75949.8481π in + (275.59π . $\sqrt{ 76093.8481 }$) in
Put the value of $\sqrt{76093.8481}$ = 275.8511339 in formula
75949.8481π in + (275.59π . 275.8511339) in
Mulitply the 275.59π and 275.8511339
75949.8481π in + (76021.8140045π)
Add 75949.8481π in and 76021.8140045π in
The result can be shown in multiple forms
