Surface Area of Cylinder Base Radius 81 foot by height 10 inches is 20813.4899915 foot2 or 51122.34 inches2

The Surface Area of a Cylinder is equal to the sum of the areas of the bases each having an area of π ⋅ r2, plus the area of the side. The area of the side is equal to the area of a rectangle with length 2 π r (the circumference of the base) times the height. Surface Area of Cylinder Base Radius 81 foot by height 10 inches is 20813.4899915 foot2 or 51122.34 inches2.

Steps:

Given that Base radius(r) = 81 ft and height(h) =10.0 in

The Surface Area of Cylinder = 2π .(Radius)2 + 2π .(Radius) . (Height)

Substitute the values of the radius r = 81 ft and height h = 10.0 in into the formula. Pi (π) is approximately equal to 3.14 .

      Unit Conversion of Width 10 in = 0.8333333 ft

10 Inches is 0.8333333 feet

To convert Inches to Feet

we know that, 1 Inches = 0.0833333 Feet or
                         1 Foot = 1/12 foot

To convert Inches to Feet, divide the inche value by 12.

Result in Foot: 10 × in/12 × ft/in

Cancel The Comman factor of in

Result in Feet: $10\above 1pt12$

Divide the 10 by 12

Result in Feet: 0.8333333 feet

∴ 10 Inches = 0.8333333 feet


2 . (π) . (812) ft2 + 2 .(π) . (81) ft . (0.8333333) ft

Raise 81 ft to the power of 2.

2 .(π) . (6561.0) ft2 + 2 . (π) . (81) ft . (0.8333333) ft

take common 2.π from the equations

2.π (6561.0 ft + (81 ft . 0.8333333 ft))

Multiply 81 ft and 0.8333333 ft

2.π (6561.0 ft + (67.4999973 ft))

Add 6561.0 ft and 67.4999973 ft

2.π (6628.4999973 ft)

Multiply 6628.4999973 ft2 and 2

The result can be shown in multiple forms.

Exact Form

Area = 13256.9999946.π ft2

∴ Surface Area of Cylinder 81 ft by 10 in is 6628.4999973.π ft2

Decimal Form

Area = 20813.4899915 ft2

∴ Surface Area of Cylinder 81 ft by 10 in is 20813.4899915 ft2

or

      Unit Conversion of Length 81 ft = 972.0 in

81 Foot is 972.0 inches

To convert Foot to Inches

we know that, 1 Foot = 12 inches

To convert Foot to inches, multiply the foot value by 12.

Result in Foot: 81 ft × 12 × in/ft

Cancel The Comman factor of ft

Result in Inches: (81 x 12 in)

Multiply 81 into 12

Result in Inches: 972.0 inches

∴ 81 Foot = 972.0 inches


2 . (π) . (972.02) in2 + 2 .(π) . (972.0) in . (10) in

Raise 972.0 in to the power of 2.

2 .(π) . (944784.0) in2 + 2 . (π) . (972.0) in . (10) in

take common 2.π from the equations

2.π (944784.0 in + (972.0 in . 10 in))

Multiply 10 ft and 972.0 ft

2.π (6561.0 ft + (9720.0 ft))

Add 6561.0 ft and 9720.0 ft

2.π (16281.0 ft)

Multiply 16281.0 ft2 and 2

The result can be shown in multiple forms.

Exact Form

Area = 32562.0.π ft2

∴ Surface Area of Cylinder 81 ft by 10 in is 16281.0.π ft2

Decimal Form

Area = 51122.34 ft2

∴ Surface Area of Cylinder 81 ft by 10 in is 51122.34 in2
